Quite simple - if we don't accomodate a 64-bit file capability format
in 2.6.24, then you won't be able to run certain binaries from a
slightly newer distro on plain 2.6.24.

Whereas having 64-bit *process* capabilities in 2.6.24 or not makes no
difference if you want to run a slightly newer distro on 2.6.24.

I realize you don't want to do that anyway (and actually I don't want to
either), but some do.

Ok.
