Yes -- but I don't think this is something we can change at this point.
It's likely to break various things.

So if you want to do font locking things in the minibuffer, you have to
use minibuffer-setup-hook (or one of the other hooks) and set things
explicitly.

So I don't think there's anything to be done on the Emacs side here, but
perhaps I'm misunderstanding what this report is about?
