@jwildeboer I've been contributing/following a few big projects that only use mailing list based contributions (Yocto, U-Boot bootloader, Linux kernel, libcamera, Buildroot). The last few years we've seen a lot of people voicing their discontent at that workflow and requesting we do everything with GitHub/GitLab "or else you will never get a contribution from me".
So I am not sure those young people are that interested in that old workflow.
@0leil And I support them with that. The very old workflow of creating patch/diff and sending that around is dark magic :) With issue and PR management a la Github/Gitlab/Gitea/Codeberg a lot has become a lot better.
