A friend once told me that you need to know 3 slavic languages to understand all of them very well. I learned that to be true from my own experience.

If you're born in a slavic country, learning second and third slavic language can be a matter of few months.

Perhaps, the value such language comes in that it could be designed to cut this process down to simply learning one additional language.

The point is, you don't need another language to speak with other slavs. Most slavs can understand each other you just need put effort into it.

Such language can perhaps broaden your ability to understand each other while speaking your native slavic language, instead of being a replacement language for all.

That's where it could work in my opinion.
