If a bug were to make it into CentOS Stream, and identified before RHEL 
8.4 was released, would an updated/fixed package be produced and placed into 
CentOS Stream?

If a bug were to make it past CentOS Stream and into RHEL 8.4 and the bug 
is then identified and fixed after the release of RHEL 8.4 would an 
updated/fixed package be produced and placed into CentOS Stream in the 
same timeframe or only if/when updated packages and their dependencies 
were made/released into CentOS Stream for updated features for RHEL 8.5?

If the same happened in the previous question but was in a package or set 
of packages that was being rebased in 8.5 would it work the same way?
