I'm the presenter of the talk, but not an io_uring kernel developer or security expert.

The io_uring implementation is complex and the number of lines of code is non-trivial. On the other hand, as code matures and the number of bugs being reported falls, the trade-off between functionality gained and risk of security issues changes. More people will decide to use io_uring as time passes. People already rely on much larger and more complex subsystems like the network stack or file systems.
