Yes. I'd strongly advocate for not adding test expectations. I've seen too
many patch authors adding test expectations and then forgetting about them.

However, there is a practical problem that the commit queue uses Chromium
Linux port and rejects patches that need rebaselines unless the authors add
test expectations.

It seems like this is what you were saying as your general statement as
