Why don’t they take the Linux approach? A browser is like an OS. Linux continues to accept public contributions, through an esoteric process that discourages lazy contributors: https://www.kernel.org/doc/html/latest/process/submitting-pa...
The only problem with that nowadays might be that AI can do all the incantations that formerly acted as gates to contributors.
The Linux approach is under pressure too. Maintainers are beginning to warn about too many contributions and too much churn to review it all.
One commit per logical change, `git send-email` instead of `git push` and open a PR. Sending patches is not the difference maker here.
Linux has WAY more maintainers, and many of them just reviewed other people's commits for years. They had a crazy amount of contributions even before AI.
