I agree.

AL> Thoughts?

I think it's a good idea.  I'd rather see it in the client than in
Xend.  If some GUI app wants to have a configurable limit that's easy
for the user to access, then it'll just end up minding the limit
itself, and call create() with the force flag each time, which defeats
the point anyway.
