An interesting side point is what some ISVs actually do. When RHEL 3
was released, Adboe made a version of Acrobat Reader that ran on RHEL 3,
and supported it with various updates for security.

However, as time has passed, they have officially EOLed the version that
ran on RHEL 3, as their only current version (with security fixes, etc.)
requires an entirely new GTK/Pango/etc stack.

I suspect there will be plenty of stuff in EPEL that will eventually
be frozen to the point where it may only get a backported security
fix or two, simply because newer things just *will not build or run*
on that version of RHEL/CentOS.
