Opinion on crafted languages:

I'm really sceptical that any crafted language will ever actually work if one of those don't happen :

- a gov decide to make it official language and enforce it's use at the expence of the country previous language.

- the gate keppers stop being rigid about the rules and let people who use the language decide what works better for them, and adapt the rules.

I understand the later might bring some confusion at the beginning, but languages need to adapt to the people who speak them, not the reverse.
