That sounds even better, since that will allow me to detect whether the
capabilities thing is supported without having to call a (possibly
nonexisting) ioctl(), simply by checking for the existence of a file.

also, I don't think there will ever be something which we might want to
know about which wouldn't be possible to express through the use of flags...

This end should point toward the ground if you want to go to space.

If it starts pointing toward space you are having a bad problem and you
will not go to space today.
