I'd be happier if you actually provided it with a better description 
and/or updated drafts along.

The glep54 doesn't state anything about how/where the specific revision 
is stored nor what the live property is and it implicitly 
provides/triggers in the package manager.

The main technical objection could be stated as "does nothing beside 
giving a token to describe infinity for a version component as version 
suffix".

The actual draft for the live templates is present at

http://dev.gentoo.org/~lu_zero/glep/liveebuild.rst

And should cover the concern you raised here beside the following

Having =cat/pkg-ver.live in package.{use, keywords} would translate to a 
sort of =cat/pkg-ver* but would be nicer putting directly an isodate to 
restrict better what you want in and what you want out.
