That's definitely true, IMO. But:
1. Warning during regexp input (e.g. regexp Isearch)
would likely, itself, be quite confusing or
annoying.
2. There are _lots_ of regexp-learning gotchas. The
case currently discussed is just one such. Any
attempt to interrupt input with some guidance
wrt what a user might be doing wrong would truly
be a distraction to lots of other users, and
even the same user sometimes, and at some point.
It could be imagined that Emacs could provide a
mode that helps users in such ways, but it would
need to be quite smart and configurable.
The differences in help level needed for different
users make that alone problematic. Ideally,
perhaps, such help would watch a given user and
learn over time (machine-learning) just what
kinds of help might be most appropriate.
