It is a novel concept, but why not just try it?  Back up your cygwin
directory, install a new version, and see if there is any difference.
If you don't like what you see, then restore the directory.

It's either that or trust some random mailing list voice to say yes or
no and then find out for yourself just how authoritative they really
are.  Given that every installation is different, no one is going to be
able to give you a definitive answer anyway.
