That is one use case.  The other, no less important one, is when the
user thinks his/her Emacs is built with tree-sitter and has the
relevant stuff installed, whereas the reality is different.  Silently
doing nothing in that case is hardly TRT.

So if we want to solve this, we need to find a solution that fits both
of these use cases.

I don't find it strange at all.
