My reasoning was to always leave a ref to the relevant change. Possibly, including the PR if present to be able to read the discussions.
Given that this release is the only one which is "in transit" from Phabricator to the GH PR workflow, PRs are not always present, hence I opted for linking the commit.
I wanted to avoid referencing Phabricator revisions, as its being phased out AFAIK.

The PR/change is helpful for the users to see concrete diffs/examples how test code was changed, or how certain flags were used. I figured, its not too intrusive, so I opted-in for those.
