I do believe it's relevant and appropriate for the
release I reported it in.

If you use a later release, and you want to investigate
whether it's relevant and appropriate for that release,
feel free to do so.  If you don't want to do that, don't.

And no, it's not "on" a user to investigate that.  It's
not on anyone.  If you want to do that, do it.

And no, it's not "my" bug report.  It's a bug that I
reported.  You're welcome.
