I've seen in some areas of LLVM someone committing a test for a bug which is marked XFAIL, and then the PR fixing it would remove the XFAIL. Is this what you had in mind?

What's difficult with this in MLIR is that we haven't been in the habit of having 1 test per file, but instead grouping them, so you can't just XFAIL one test cases in a larger file.
