There is no prohibition against slipping with flaps, so it is legal and in the Maule, seems reasonable. Cessnas had some sort of handling problem there, so that is where the don't slip with flaps frame of mind comes from.
That being said, I don't resort to slipping with flaps very often. It makes for a lot of buffetting of the airframe, flaps and wings; takes a LOT of pressure on the rudder and doesn't result in a much steeper approach. It's a fairly small rudder trying to overcome a very large vertical stabilizer.
With my M5-235C, I get better result by slowing up considerably. It feels strange at first as the speed bleeds off and you keep going higher than your desired glide path, but then once you get to 1.2 Vso and below, it really starts coming down. Just be ready to arrest that high sink rate by dropping the nose to regain speed and probably adding a shot of power.
Play with the low speed regime a bit at altitude and get the feel of it, then work progressively lower.
