Sure. But I could *really* piss a lot of people off if I removed
libncurses5 and libncurses6 and released libncurses7 instead (and even
moreso if I release "empty" libncurses5 and 6 packages to force the
deletion of preexisting cygncurses5/6 DLLs).
I don't think it's reasonable to assume that ONLY the packages
distributed by the cygwin mirror system matter -- even after all
"official" packages have migrated to the new cygncurses7.dll, "external"
progs still might require cygncurses6/5 for a while.
Just because it's possible for Bob to recompile "HMD" doesn't mean that
we as maintainers should arbitrarily and needlessly force him to do so.

Sure -- and I figure I'll keep it around for about 6 - 9 months. But
I'll never release an empty "libreadline4" package -- that's just
needless meddling with the user's system.

Sure. But Bob previously ported HMD to use -lregex, and now his binary
requires cygregex.dll. If he is distributing HMD (with sources, no GPL
violations here) now he must immediately "un-port" and recompile --
because new users can't get cygregex.dll anymore. I don't think we
should be that dictatorial to folks who distribute derivative (but
GPL-compliant) packages that piggyback off of cygwin.
To sum up: I think you should release "regex-4.4-3" that only contains
/usr/bin/cygregex.dll -- and nothing else. (this guarantees that new
packages cannot acquire a dependency on cygregex). And then just let it
sit for several months, so that the "Bob's" of the world have a
reasonable amount of time to recompile their stuff.
