Comment (by ezyang):

 mgsloan, how much of this do you want to fix for the upcoming 8.0 release,
 as opposed to backports for 7.10?

 I think your life will get better when we unify IPIDs and PackageKeys, so
 that there will no longer be any distinction. If you're also willing to
 wait for 8.0, I am sure there are many affordances that could be added to
 hpc's API to make things better.

 Ultimately, I do think it is right for GHC to output Tix files based on
 the "package key" (which happened to just be the "package id" in the past,
 but only accidentally).
