Such changes are not really a parallel stream of development; it's
not appropriate to use CVS branches for this type of thing.  Use some
other configuration mechanism to represent these variations in a single
code stream. 

This is similar to targetting multiple platforms. If you wanted each
release of some program to run on half a dozen platforms, you wouldn't
create half a dozen branches.  Rather, you would make use of tools like
conditional compilation mechanisms built into your programming

Ask yourself whether this is a process you want to repeat each
time you release.

Isn't it too late to be making changes? You have a release point,
which  means that the normal configuration of the software, as
well as the customer-specific configuration, should have been already
put through testing.
