I just wanted to bump this up as the most important part of my original
message, since it seemed to get lost multiple times in discussing whether
these tests should be optional.

Please go through the tests before changing any of the spec text, and make
sure it lines up with what the tests are testing.

Edits for clarity would be helpful, but please don't remove any language
just because you don't understand it. The tests should help with the
understanding part, hopefully.
