Is that a big problem ? I mean probably those who need an ACK just want
to be sure their PR was not lost between them and you. It's not a guarantee
that the code will be kept till the release anyway, and I tend to think
that changing your mind after attempting a build is not different than
changing your mind 3 days later. So when this happens, you're possibly
expected to simply notify the author later saying "sorry, I changed my
mind and finally I dropped your code for this or that reason". That
should be enough to cover the vast majority of use cases, no ?

Just my two cents,
Willy
