No it doesn't, not if the libraries are properly API versioned.  As for
RHEL using older versions of things, you'd need to understand what their
target market is.  (Hint: you are not and you're not a paying customer
either.)

Look, been there, done that.  That was fun when you wanted to change one
kernel variable and had to build a new kernel, then take the whole
machine down for a reboot and wait an hour for it to come back up.  Or
not.

You are missing the point, entirely.  Dynamic linking is not about
saving space or making things slower or faster.  It's an essential part
of configuration management for a system that's built from many parts
that are built and updated independently.  Static linking cannot solve
that problem.
