Don't think so.

I think Kazakh has s instead of sh as in other Turkic languages but
I do not believe there was a collapse. I think new language learners
simply learned only s.

You appear to be making the following statements, one claimed as
true, the other as your belief:

1. A change [S] > [s] is not a case of a sound changing to a nearest
neighbour.

Either 2a or 2b (I can't decide which):
2a. Under substrate influence, Turkic *s and *S both becam
Kazakh /s/. They did not collapse to a single phoneme.

2b. Kazakh child stopped learning to distinguish [s] and [S]. This
is not a case of collapse.

What did you mean to say?
