Well, that's dumping a kluge onto users; but really that isn't the
point. What we have here is a badly designed and badly implemented
feature, and we need to not ship it like this so as to not
institutionalize a bad design.
I like the proposal of a boolean because it provides only the minimal
feature set of two cases that are both clearly needed and easily
implementable. Whatever we do later is certain to provide a superset
of those two cases. If we do something else (and that includes my own
proposal of a straight lock timeout), we'll be implementing something
we might wish to take back later. Taking out features after they've
been in a release is very hard, even if we realize they're badly
designed.
