And I think that's doing the maintainers a disservice.

"Random strangers, please don't have your agent send us PRs, we don't want to review it" -> yeah, totally reasonable open source maintainer behaviour, doesn't update my perception of the project at all.

"All code in this repo must be written by hand" -> This is probably not a serious project and I'll make a mental note not to depend on it.

If servo is really in the latter camp I'd actually say that's negligent at this point. A browser engine that doesn't have agents scanning for and fixing vulns is totally unacceptable.

"Code must be written by hand" is not at all incompatible with "use agents to scan for vulnerabilities", or for that matter "use agents to find bugs", "use agents to help with profiling to give you data for optimization", or any number of things that aren't writing the code for you.
