I agree; I was surprised to discover this info embedded in the
Makefile.am.

+1 to moving the documentation to the tests themselves, that's probably
the first place one would look, and it would make it easier to keep the
notes up to date along with the test.  If the explanations include some
common tag, then we could search for tests with xfail images but no
explanation, and deal with them.

Also, I was curious if either of you knew if those documented rationales
are still valid with the current codebase?
