OK, well said.  I agree with the potential pitfall you're concerned 
about.  We "lucked out" with libpopt0 because, though obsolete, it 
requires another package: popt.  The mechanism here allowed the popt 
library's previous name to be used by other packages until they're 
updated to refer to the new name.  No functionality was lost by 
obsoleting that particular old-named package.

I will update the cygutils* packages to refer directly to popt rather 
than libpopt0 but other maintainers will act on their own schedules.  
Problem reports do help with prioritizing, of course :).
Thanks for the report,
