Would be great if 1.20.2 support was added, as this is one of the mods blocking my upgrade.

Version bump requests are not helping. Mod authors are usually aware if a mod needs an update, and those bumps just annoy them.

Getting such requests doesn't speed anything up, just wait.

It's still an issue, even if an author is aware this let's people know it's already reported

You're just saying the same thing.
A lack of support for a version is still an issue that should be reported.
I'm on 1.20.4 but 1.20.2 support seems to have been fixed with https://modrinth.com/mod/debugify/version/1.20.2+1.0

Mod-Authors know when an mc-update comes out.

I spent the last 2 Days fixing a single mod for 1.20.3, just because Mojang decided to make Ui changes again for no reason.

If an update takes longer than expected, you can usually thank Mojang for it.
