Yes, and more importantly, _user_ code can use overlays in the minibuffer (as in
any other buffer, AFAIK).

It is great to point _also_ to existing Emacs source code in this regard, but
this is really inessential (irrelevant).

What's important wrt overlays here is that users can create and use them, not
that some existing Emacs code might do so.

What users can do they will do.  Emacs should do its best not to crash in such a
context.
