Hope this helps,
Thank you a lot that really helps.
So as I see it: bringing in act the wrappers makes it incompatible with the flag, but we need it to non-leaking slippery written code of connect in other cases. IMHO we just can enforce the flag in case of wrappers, so client either writes something on his knee or use async operation (where some rules must be obeyed).
Making something more I think do not worth it because: 1) in 10.2 C/C will replace the library and it has no the problem 2) we should no make huge changes before 10.2
