I think making the lock prompt more extensive would be pretty
annoying -- we only use yes-or-no-p (and related) when doing something
destructive or dangerous, and stealing the lock isn't that dangerous.

So I think the current level of prompting is fine, and if you want more
prompting, then it should be easy enough to redefine/advice
ask-user-about-lock to be harder to get past, and I'm closing this bug
report.
