If the tags implied by another tag were documented in a standard form,
in a central place (so any application, editor, render, etc. could read
it) would that change your mind?

The disadvantage of explicit tagging for everything is massive
duplication of information. It also means that newcomers may not quite
get the tagging right, because they assume that a road type which is
inherently one-way doesn't need explicit tagging.
