Is there any improving the test suite to catch this kind of thing with the refleak bots? A quick glance suggests probably not, but it's worth at least getting a proper answer to the question written down :)

I think a few of these could be caught with a test, yes. It doesn't feel extremely high value (these particular paths aren't likely to regress), but I can add some if you like.

I'm in no position to make that value judgement :). More test coverage is generally better, but if they're not worth it they're not worth it.
