Well, it feels normal to me, since I've been doing it since I got back into cycling about 5 years ago. And yes, usually I will employ a "mountain bike" RD to do this, or rather anything with a long cage, including vintage Shimano 600 (both Arabesque and 6200 series), Crane, SunTour Cyclone (three different generations), SunTour aRX, VG-T, Blue Line, Shimano Tourney, 105, etc...
It's a good way to avoid the extra hassles of going to a triple up front (which I also do a lot, because I like to tinker.)
But it doesn't
necessarily take a triple or a long-cage RD. Here's my Super Course in a previous configuration running a 34 cog with an Arabesque short cage RD. With the
exactly right combo of chain length, RD hanger length, and position in the dropout, it worked just fine.
