I've found that of recent times, when seated in an overwing exit row I've been asked if I'm happy to assist, and "do I understand the briefing card?". That's been the extent of the special attention.
Surprisingly there was a guy next to me who was so big he sought my assistance to do his seat belt up. He couldn't have assisted because of his physical size, which was such that I doubt he'd have been able to exit the aircraft, other than through the normal doors.
