I know there are many problems with IALs so why not make a zonal auxlangs.

I think theyre a fantastic idea and people should make more of them, a conlang that is mutually intelligible between natural languages of a certain group like Turkic, Iranian, and Indo-aryan for a few examples.

People want to learn a language for economic/cultural interest and I'm sure theres people out there who's interested in Malay, Polynesian, Iranian, and Indian cultures

Is there a reason why there's not much of them, I mean conlang-ing is a niche and obscure hobby, but is there a reason for it.

Are there arguments for and against ZCLs and where can I find more arguments about IALs too, I don't like IALs, but I'm interested in the arguments for and against them.

Sorry if I am unclear Thank you in advance!

Edit: It seems that I am not clear in my text so i'll summarise

-Why isn't there more Zonal Constucted Languages, Zonelangs, Zonal Auxlang etc is it because conlang-ing a very niche and obscure hobby or something else

-are there critisisms of ZCLs

-where can I find more of it

Let me define a ZCL

✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️ A constructed auxillary language designed to be neutral, mutually intelligible regional lingua franca for a certain geographic (Mainland Southeast Asia, Caucuses, Oceania etc) or a lingustic group (Iranian, Semitic, Berber, Turkic, Malay, Indic, Baltic, Finno-Ugric etc) ✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️✅️

Edit: I highlighted it.✅️

Edit: I want to make a few hypothectical senarios

Lets say there's an average joe and will call him... Joe Now let's assume Mr. Joe's native and only language is English and Joe wants to be bilingual, he doesn't have a particular language he wants to learn.

Hmm maybe he'll want French, so he can read those fancy menus at them fancy restaurants his wife keeps dragging him into.

Maybe he'll want to learn spanish, so he cut short those robo-assistants out so he can finally talk to a human

Then he stumbles upon a wiki article "what's this?" Joe saids "Pan-Romance Language?" He repeats, he is intrigued he clicks and reads the article "a Constructed Language?" He parrots he's interested and does some research and discovers interlingua and he's fascinated by it and weighs in the languages he would learn "French" He picked randomly "or Interlingua" he raised his oposite hand. He debated with, learning standard French he would spend 3-4 years to be proficient and only understand French and he's not really into French or He learns Interlingua a language that not restricted to French culture, He can choose which language he wants to learn more of instead of having to stick with french. So which will Joe choose?

"Interlingua" He said assuredly

Senario 2: Meet Garpancha, an Ethnic Evenki Woman and a Russian National, Garpancha is apart of the Tungusic-Speaking peoples of which whom numbers around 75,000 speakers and Evenki itself numbering 16,000 and it is a severly endangered language.

She doesn't want her language to die out, so she works with activists to help and keep her and other tungusic languages alive and well.

She became a Professor at Tomsk State University to teach others about her language and peoples.

She campagins to spread more awareness, but it is difficult to be able to communicate with other tungusic speaking peoples in more isolated and rural areas due to a lack of a common language.

she stumbles upon something a PDF file titled 'Jerry Norman's Common Dialectal Chinese' She's curious and she clicks it and reads through it she is amazed that such a thing exists, a book about a contructed language that is mutually intelligible between different Chinese languages, She heard of esperanto and read a wiki page about it, but it didn't held any practical use for her, but Jerry Norman's book inspired her to make one aswell, after through research about making a constructed language of course.

Thanks to her conlang she is able to effectivly communicate with other tungusic speaking peoples, sure 75,000 people isn't much but theres more power in numbers.
