This is only an issue if you run a clipboard hoarding program like klipper 
that tries to copy clipboard as soon as a program changes it.

The default (i.e. no klipper) don't really care what the selections are 
called.  They are all treated the same by the X server.  You can create your 
own selections and they will be treated just as PRIMARY/CLIPBOARD/SECONDARY by 
the X server. The drag and drop protocl Xdnd has its own selection for example.
