This looks good, but I'd suggest to wait merging until we have the new nightly version to have enough time to discover any unexpected behaviors.

Landing this, as the changelog for leak canary suggests the newer versions leverage the new work manager versions. So it would be easier to est the new behavior changes in #23082.
