We don't have a standard for this, and an undocumented patch applied
without any discussion doesn't create one. It's hopeless to imagine
that you'll ever achieve any uniformity that way. It won't last long
if you do, since you're outnumbered by committers who won't be following
whatever you think the convention is.
I'm not even sure why you're trying --- I don't think it even makes
sense to try to have a standard about this. I can easily imagine that
integer constants might read better with <literal> in some contexts
and better without in others.
