Just want to leave some reasoning behind closing this: We discussed this in our wg-traits meeting today. We basically agree that right now the chalk-integration is so experimental that things not working is basically expected. Most of the test suite doesn't even pass with compare-mode=chalk. Once we get to a point that nearly all of the test suite passes with -Z chalk, it'll make more sense to keep chalk-related issues around, particularly under the case that it's something we expect to work with Chalk, but not with the rustc trait solver. If it's a test case that doesn't seem to be covered by the test suite as is, I would expect it's better to just add it as a regular test. But that's sometimes hard to know.

(I'm going to post this to all these 4 closed issues)
