It's a catch-22: We don't want people to use a new release until all the
bugs have been found and fixed, and all the libraries have been updated.
But if people don't use it, then the bugs won't be found and the
libraries won't be updated.
I think you're saying that you'd like the uptake of new GHC versions to
be slower, which would mean fewer people would be using 7.6 now, but in
the last few days I've seen the Debian guys have had to send mails to
maintainers telling them that their packages don't work with 7.6:
despite 7.6 having been out for 5 months and about to enter the HP.
Perhaps more automatic Hackage building, with a group of people looking
at the logs of failing packages and acting appropriately, is the way
forward. Some cases (such as "installation failed due to dependencies
not being installable") you'd want to be handled automatically.
