I think partially that's because it's hard to see the goal from those
threads. Leading the intro email with "after applying use these three
steps to replicate a database" or something might help.
I also want to add that so far, to my knowledge, the feedback hasn't
fully been addressed. It's a bit hard to see progress at that pace.

I think that's a strawman. We have done actual iterative development
where the basic feature came at an early stage a lot of times. Most
And even if we decide that feature X has to be supported, having an
otherwise close-to-committable patch series, goes a *LONG* way to

My impression is that unless you *NOW* press very hard to get it into
core, there's no way to get it into 9.7. Unless you start aggressively
at some point, it'll never get in.
