Just to give some history, both coming from Johnny Hughes posts:
- https://lists.centos.org/pipermail/centos/2016-May/159328.html
state in 2016 with git repos (now not available any more) with some
considerations and in particular:
These packages were supposed to be community maintained, but no one has
done the work to try to keep this updated.  I can TRY to do this (but
not for a while), but it would be better if someone from the community
would do it.

- https://lists.centos.org/pipermail/centos/2018-October/170381.html
state in 2018 as no one (yet?) felt to take the ownership
We would be very happy to publish those RPMs if we can get them to be
maintained by the community, and maintained in a consistent manner.

Possibly one of the reasons why it didn't take so much appeal was, as I
totally agree, still coming from the first post considerations:
I personally would never do an in place upgrade on a production machine.
 Call it a personal bias.
Lastly, as you can see from reading official documentation, upstream
limitations are very strong about set of packages that are supported to be
upgraded in place.
Ensure only supported package groups are installed

and probably on your system you have many other packages / package groups
and the natural question would be what to do with them during the upgrade
in place process...
