I saw a pax go bonkers on a Q2 FA because she didn't have the ear plugs that he requested :-)
Is it official, sure...I've flown on all of them and can agree. Most turboprop flights are easier just to drive. Usually short hops to hubs. Granted the examples given of SYR, JFK and others out of CLE aren't drivable, yet those are served by other airlines with other aircraft. I do all my homework and systematically try to avoid props--but that's just me. Most fliers I find have little to no clue what kind of aircraft they're booked on, and act shocked to find they're on a bus from ABE-EWR, then a 777 to Europe.
