99% of the time it's perfectly fine to just email the maintainer with a bug report and maybe a patch.

Judging from the fact that after so many years, such a widespread (as seen in the Reddit post and here) issue still hasn't resulted in a single bug report in the mailing list, I'd say most people (including myself) do indeed consider using a mailing list to be higher friction.
If I'm not mistaken, unless you're already CC'ed by a participant, you'd have to subscribe to the whole mailing list just to receive notifications for a single thread. For an "issue" on a Git forge, participation is usually as easy as upvoting and then clicking the "Subscribe" button.
In the current age, its useful because AI will submit tickets using the CLI that don't use the form, so I can immediately close and lock them and go on living my life.
