You can already turn off execute permission either using traditional Unix
permissions or via the current, existing ACL facility.

Note that it's actually pretty hard to stop a user from executing a file, since
it only requires one file system that is mounted w/o noexec, and then they can
simply copy the file (assuming they have read access) from its original
location to a location in their home directory, or /tmp perhaps, and execute it
there.

So it would first be useful if you were to describe exactly what your high
level goal is with having more fine-grained noexec capability.  What are you
trying to do?
