I am saying that with modules and unless you want to stand up a bunch of
other things.. you are probably going to have to. However this isn't much
different from how the current CentOS-7 is.. there are no Z streams for
CentOS-7.. there is only the latest with dot releases being sort of rebased
snapshots that are built off of upstream src.rpms.. So if people have been
saying that there is no CentOS-7.7 there is just CentOS now.. then this
would be taking that one step further.

By the way, I am only +0 on this at the moment. I can see why it looks
attractive and makes certain work easier, but I am also aware it will makes
deployment different/harder. But hey ~5 years ago we had a similar
conversation on CentOS 7 minor version numbers with me arguing against
going with 7.<YYYYMM> and wanting to keep 7.<minor>.
