This would break some set behavior, at least in Portage. Specifying a single version (or better, a slot) in a set is less work than adding lines to p.mask *and* the set file(s), and p.mask doesn't appear to support "!=cat/pkg-1.0" syntax to mimic the same functionality achieved by a versioned atom in a set. It also makes sense to put packages you want in a set instead of a mask. ">=" or "<=" may be adequate if you only want one slot or version installed, but the entire point of slots is to allow multiple versions to be installed simultaneously. Versioned package names in sets achieve this.
