To be clear - the problem with the bad aesthetics is due to Moen's incorrect instructions.
The Moentrol valves come with a plastic disc affixed to the face of the valve, and this disc is clearly stamped "IMPORTANT! THIS SURFACE MUST BE FLUSH WITH FINISHED WALL".
And if one abides by these instructions (i.e., setting the valve in the rough framing with the face of the disc protruding ~13/16" past the face of the studs to accomodate .5" Durock + thinset + .25" tile), then yes, the back of your finished valve handle will have roughly an inch of gap between it and the face of the escutcheon when in the "off" position (and will surely make your wife cry).
The asthetically-correct install requires the face of the plastic disc to be roughly 3/4" *recessed* before the face of the finished wall - *not* flush with it. (or roughly flush with the face of the studs if using standard .5" rockboard and .25" tile.) This will give you about 1/4" of gap between the escutcheon and the back of the handle when in the "off" position.
And the Moentrols are not particularly "workaroundable" when it comes to this problem - removing the stainless sleeve might buy you another 1/8", but will also introduce play, expose some of the valve's brass, as well as allow the handle to spin freely over 360 degrees.
All you can do is reseat the valve, and if you're lucky, it just means a miserable weekend of tearing out the back side of the wall (which is hopefully just sheetrocked, if you can access it at all), then sawzawling your mount board and reseating further back instead of redoing your tile work.
I know this because it's what my upcoming weekend entails. Thanks Moen...
PS: I should add that my wife decided-on-and-ordered the finish/trim parts several months after I installed the valve itself, so I didn't have a viable means of testing the finished product during rough-in.
