alt Hacker Newsiirc io_uring also had some pretty significant security issues early on (a couple of years ago). Those should be fixed by now, but that probably dampened adoption as well.

Not years ago. io_uring has been a continuous parade of security problems, including a high severity one that wasn't fixed until a few months ago. Many large organizations have patched it out of their kernels on safety basis, which is one of the reasons it suffers from poor adoption.
Last I checked it's blocked by most container runtimes exactly because of the security problems, and Google blocked io_uring across all their services. I've not checked recently if that's still the case, but https://security.googleblog.com/2023/06/learnings-from-kctf-... has some background.
