No hints should trigger the autohinter, yes.

Until recently, medium.com served some Utopia CFF font (I think?!) with 
blue zones but without hints (result: no hinting). gov.co.uk also serves 
some font without hints (can't determine what kind right now). Google's 
Caladea and Carlito fonts ship(ped?) with a hinting table stub but no 
hints, but that triggered the autohinter iirc.

Blue zone/hinting table detection is a first line of defence, but you 
have to check for hints to be sure.
