Can we have it so that the bot doesn't touch the expectations for tests that are not actually new or modified? Because for intermittent failures the bot will just keep flip-flopping the expectation values between the various intermittently produced states on every update. Specifically from this push, bug 1464302, bug 1477606, bug 1473544, and bug 1474649 were all affected for no good reason. I expect the intermittent failure rates on those bugs to go up significantly now because the bot changed the expectation to what I believe is the lower-frequency state, so the "failure" will happen more often.

Also in general changing the expectation for existing annotations can hide real failures, and reduces the value of having this suite in the first place.

It;s generally hard to figure out if a test was modified. We don't have enough information to figure out if a particular support file is used by a particular test, so we can't reliably work out which tests were actually modified by a particular push. In addition harness changes may also affect test results, and we have no way to determine which tests are expected to be affected. I know this situation isn't ideal but I can't think of a realistic approach to improve it in the short term.

We already go to some lengths to determine which results are intermittents (multiple try pushes + retriggering failing jobs after the metadata is updated to see if we flipped things the wrong way). In this case we accidentially skipped that second try push, so the result was worse than usual. But in general having many intermittent tests enabled is a problem, not just for the metadata update. We should try to fix the underlying problems where possible.
