For that we'd also want to move fexec(ve) into the kernel space.

I agree this would be useful, but it's a separate issue.

I don't think it is.  The whole point of O_EXEC is to support fexecve.

Without moving it to kernel I can't see how you can make it strictly
conforming to this requirement in Posix that the file descriptor 
must be valid for executing.

Fortunately enough the kernel implementation is trivial.
