Yes they have. I have on several occasions, as have other people on this
mailing list:

I even *fixed* that already, but you decided to take it out before
committing. I then added it to the list of must-fix items in the TODO
list, but you took that out too. I have no objection to doing things in
smaller steps, but this *is* a must-fix item before release. I still
don't understand why you took it out, nor why you're objecting to that.

So what was the clear result?
If you're looking for things to do, I agree with Greg Stark that the
removal of max_standby_delay=-1 option is not good. That should be fixed
too.
