Whereupon Server SIG/WG perform an evaluation of Btrfs for their use

Fedora 35, if folks really want it to happen.
Theoretically, it could. But practically, I don't see it happen. The need for
discussion is too great. And not everyone is as convinced as you are that BTRFS is the
non-plus-ultra for all possible use cases.
Server SIG can do anything they
want. Red Hat is doing the same.
Nevertheless, coordination and cooperation is at least very desirable (in fact,
indispensable). And is is not just about who is paying the bills. Beyond this crude
economic dimension, Fedora benefits from the reputation of being upstream for RHEL (and
vice versa, for sure). A defiant "we can do as we like" is not helpful.

My opinion is to not worry about the process in advance of arriving at
the hurdle. You jump over the hurdle at the proper time. The vast
majority of the process is about technical features liabilities.

And when we address discussion and evidence:
Not often but sometimes folks ask "where has all the space gone?"
following a Server installation. They're not expecting or maybe not
discovering, that quite a lot is held in reserve in the VG.
As said before, I agree with that, at least for the most part. I use BTRFS myself in LVs
to use specific capabilities. Still, I'm against converting "with a flick of the
wrist," so to speak. It needs careful preparation. And one possible outcome is also,
not to switch to BTRFS. I don't think it is a given that a switch is right in any
case. That is perhaps the difference between us.

had?) an agreement to align (or try to align) Server Edition and Cloud. That was 2 or 3
months ago. Regarding to that agreement, it is a step into the wrong direction.
Is there a Server or Cloud meeting with minutes that this discussion
happened in? Or email thread you can point to?
Michel gave you the link. And there were several brief comments about that in previous
meetings and also before that reboot event.
And when we address discussion and evidence: What I miss is a prior detailed discussion of
this change in cloud WG and coordination with other possible affected areas, e.g. server
or CoreOS. Cloud Working Group did not happened for years, then there were a few short,
sparsely-attended and content-dry meetings. A range of existing problems, starting with
lack of documentation. A hesitancy to make any change currently to the cloud artifacts
(expressed by Dusty Mabe at that March meeting, 3). And then out of nowhere the file
system conversion, a very central element. To me, it seems like a playground for
missionaries to gain ground, certainly not like a considerate and methodical long-term
design.
