It is not the same as Rawhide is all I am saying.

It is based on the current release and it is being modified for some reason.

That modification can be a bugfix from a reported bug, it can be an
enhancement for a given package or it can be a security update.

Each of these updates will be rolled in one at a time.

It is what will eventually become the next rhel source code in a few
months for the next point release.

Only you will know if this will work for your situation.

We do have CI testing, which will be beefed up to be similar to the
testing RHEL actually does right now before release of packages for the
'released version' of RHEL.

Will bugs get though .. sure, they do now into RHEL.

But I will absolutely say that the things they are rolling into RHEL 8.4
in a few months are not inherently less stable or less secure or
whatever else you want to call it .. when compared to other Linux distros.

The process that Debian would use to roll in bug fixes or Ubuntu would
use to roll in bug fixes would not be significantly better or more
stable or more secure.
