Wearing my RM hat, I've already mentioned that I'd be perfectly fine 
with 8.6 having a case‑insensitive `ini_get_all()`.

Wearing any other hat I might have, I agree that keeping extension names 
case‑insensitive makes far more sense.

Another example is `composer.json` and its `ext-*` dependencies, which 
are also generally written in their lowercase variants.

To me, this would be one of those useless BC breaks that make the user 
experience worse instead of improving it.
