and are pretty much the only open technology that is sufficiently technology-agnostic and interoperable.
what should be the alternative, facebook comment threads?
They are open, technology agnostic, interoperable, and most news readers are way better at threaded discussions involving more than two people than almost every email client.
How hard it is to open N separate issues and link them to the original one? It's exactly as much effort as sending new emails.
TC39 uses GitHub: https://github.com/tc39/
There's also the IETF datatracker, and various sites cobbled together to show the mail threads (eg. https://mailarchive.ietf.org/arch/browse/acme/ ) and states of various RFCs. And basically to manage work.
Email is great, and it's enough for IETF workgroups, but it's just a communication channel, it's far from an efficient tool to organize (track, show, share, plan) work.
Gitea, GitLab, GitHub, Bitbucket, Discourse literally everything else similar to those is more usable than the pieces of turd that mailing lists are. I instantly assign a negative score in my mind to all projects that still find them in any way usable.
Sounds like the filtering works!
Don't come crying when you can't find any contributors, it's your own undoing.
It really is gatekeepy to keep something that is only attractive to a very select group of people.
> Those that grew up with mailing lists naturally find it more comfortable for them.
Yeah, which is exactly why I called it a massive red flag. It's the unwillingness to suffer short-term discomfort over long-term benefit of new contributors and overall better user experience and accessibility.
