Since this discussion appears to resolve around "test" versus
"production" releases would it not be better served if there were two
differing base paths, one for production and one for test?  If that
occurred then there may be more testers as what is used for production
isn't borked by a test version of some package or even Cygwin itself.

So for example C:\cygwin64 serves the production path while
C:\cygwin64test serves the test path.  This would help segregate test
from a production environment without worrying the user with needing to
revert back if something fails.
