I was hoping for a policy that would have this as a side effect, but perhaps it's good to decide on this individually as well.

Yes, #92 is about overall policy, but this seems like low hanging fruit so worth splitting out into a smaller item.

web-platform-tests/wpt#29985 is a PR with the actual code changes to remove the support for testing testharness without the Promise constructor.

Looks good, go ahead and merge

It looks like the test cleanup for this never happened, so actually adding dependencies on Promise is still hard. I've sent web-platform-tests/wpt#33507.
