Thank you for your considered response. If it is not an improvement,
then there is no reason for the change, is there ?

Whatever the original cause introducing sub-version numbering, that
usage has become a clear progressive indicator of collections of updates
within the major version.

I image the vast majority of Centos users will not risk doing
non-standard updates on their production systems so your above concern
is unlikely to occur.

I can not look at something labelled Centos 7.2169 and instantly know if
it is Centos 7.1, 7.5 or even Centos 7.10.  What's the latest version of
Centos 6 ?  Is it 6.32167 or 6.32782 or 6.32783 or should I be typing
6.23783 instead ? Confusion is not clarity.

If Centos is "functionally equivalent" to RHEL then common sense must
dictate that the sub-version numbers should be compatible too.
