That can be done, but reading https://lwn.net/Articles/902466/, writers of security tools are unhappy that:

- io_uring initially was conceived without considering security or auditing tools

- io_uring later was changed to allow ioctl calls, even though security people do not like ioctl because what its arguments mean depends on the device being called (possibly even on the version of the driver), not on the type of device, and often is poorly documented, making it hard for a security filter to decide what to do with a command.

That also made them fear that similar security-breaking changes might be made in the future.
