CentOS - Jan 2021 - CentOS Stream suitability as a production webserver

Didn't the CentOS Vault repo ensure that every package ever published was
still available?

to is that it doesn't matter if you're talking about CentOS today or
Stream in the future: If you want to be able to roll back, you need a private
mirror that keeps the package versions that you use.  If you don't want a
mirror, then you need to build, test, and deploy complete images rather than
making incremental changes to mutable systems.  None of this is new, it's
always been this way and people have just accepted it.

You should come to realizing that things changed. They are not what they were.
With all fairness no one can say what will be true in a short future to come.

Yes, it did, but that is not the intention for CentOS Stream moving 
forward. Only packages in CentOS Linux are moved to the vault at point 
release time. CentOS Stream only ever has the LATEST package version and 
nothing else.

There is a bug filed for this issue here:

https://bugzilla.redhat.com/show_bug.cgi?id=1908047

If it is likely to be an issue for you, please make that known. The more 
people this affects, the more likely it may be addressed.
