Searching the USPS also isn't really an argument here because their database is proprietary so apologies for me completely ignoring a source we can't use at all.

Only other person who's edited as much locally as I have is NE2 but he's the first person banned for life from OSM (and good riddance in their case).

It's mostly just you and me on this one.  Based on other cities that also have the directional thing going on, I'd prefer to keep that information completely intact.  I'd like to move forward on having addr:* information added to streets as hints for validators, though, since this makes sense entirely too often here (case in point, in Sapulpa there's a signed "Officer Larry W. Cantrell and Mister Charles L. Cantrell Memorial Highway" where the finger signs say "New Sapulpa Road" and the USPS says "Highway 66".
