Everybody wants everything to "just work", for their own ( in a lot of
cases unspecified even to the themselves ) definition of JW.
Developers normally want to be told what "just work" means when
developing something.

That been said, I'm not sure making it ( deferred constraint act like
immediate ones during upserts ) work is even a good idea. If it can be
conditionally enabled with a simple set and implemented in very few (
< 20 ) lines of code, ok for me , otherwise I would prefer the reduced
bug surface.
