Actually, this has always been true.  It's just that it was done in the
form of patch resources internal to the System file prior to the release of
System 7.1.  It used to be that, in order to save disk space, one could go
into the System file with ResEdit and remove the various 'PTCH' resources
that didn't apply to the particular machine you happened to be using.

The System Enabler scheme is simply a somewhat cleaner method of
accomplishing the same thing: you now have a "generic" System file, with
the various hacks segregated in the Enabler.
