I'm not convinced that we should try to build packages at any price.
If they're likely to cause problems in a standard environment on a
user machine, then isn't it better to see this reflected on Hackage?

Does it produce a usable package and environment, or does it just
work, but leave everything broken? I agree that using
--force-reinstalls on Hackage might be an acceptable option, and it's
probably better than using --avoid-reinstalls by default. However, it
may still send the misleading message that a package "builds just
fine" when it practice it doesn't.
