Back in September, I collected some statistics on states that use
something other than the state abbreviation in way refs:
<https://lists.openstreetmap.org/pipermail/talk-us/2014-September/013604.html>
tl;dr: 97% of Michigan's state routes are currently tagged with M or M-,
and a couple other states are also contrarian in this regard.

I think NE2's ref efforts have largely been undone in states where
mappers disagreed. (I undid several of his edits where he tried to
reduce refs to parenthesized numbers.) But in the case of Ohio, we were
already using "SR" and have continued to use it. (Ohio's shields have no
lettering on them, but blade signs, variable message boards, etc. do say
"SR".) Next door in Indiana, I think "IN" has pretty much taken over.
In general, if you'd like to make systematic changes to data that seems
intentional, it's a good idea to reach out to the mappers who entered
it. And if you decide to go ahead with any ref editing, be sure to add
any missing relations and relation roles.
