For the last couple releases, I generated the list of bugs to add to release notes, and yes, I typically exclude backports for that reason (it isn't perfect, but it also excludes the issues labeled with the `hgupdate-sync` label, which can be added to indicate an issue synced in from a prior release).

Here is the same filter I used in the past, updated for JavaFX 16 for comparison:

https://bugs.openjdk.java.net/issues/?filter=40381

You'll notice that it excludes test bugs and build issue (so the "GitHub Actions" bugs don't show up, for example)
