what i didn't say (and should have) was that he only does bare route 
numbers for state

as a software person, i dislike inconsistency in representations 
(prefixes vs no prefixes),
but because there aren't strong controls over how ref tags are edited, 
it's something that
has to be lived with, and code simply has to be robust enough to not 
break when
presented with such things.

i personally am slightly neutral on the nature of the state prefix. in 
NY, using the postal
prefix makes lots of sense as everyone in this state knows exactly what 
you're referring
to. but i grew up in Florida, and the SR prefix is the norm when 
referring to state highways
there. MI and TX are unique of course, as others have posted in this 
thread. i don't know
that a truly consistent US-wide concensus is actually achievable.

i think i feel a longer essay about tagging (and what we're tagging for) 
coming on, but i'm
not going to write it tonight.
