Any comment on which version this might be included -- if it is deemed suitable for merging?
This way I could add the version_added field to priority parameter docs.

That would be 10.0.0 - thanks for checking

Thanks. I recall having to wait for a "non-patch level" (major/minor) for new features in the past and I'm not sure what version is planned next. Will add that in the commit as well.

Usually #582 has information on when the next major/minor/patch releases will happen (and thus also which next minor/major release will there be). I apparently forgot to update the top post the last time (it's updated now), but if you scroll to the end you find that information as well, just a bit spread out :)
