The thread drift is perhaps getting a little out of hand but permit me to add that I once measured oil temperature in a "deep" sump over the course of a road run, it never climbed above ~65C. Of course oil temperature at the bearings is another matter altogether - I can only say that it's never given me a problem (on a pressure-fed touring engine).
The flange at the front fouls the frame and some day I will get around to studying it and doing some careful trimming. For engine out I simply remove the sump first, then re-fit it in situ.
The upside of a "deep" sump - possibly true of the shallow cast sumps to some extent - is that they help stiffen the crankcase, though this is very difficult to quantify objectively. But more importantly they can carry more oil! My oil pressure gauge pipe broke loose on a stretch of cobbles in Germany and I lost about 5 1/2 pints over a kilometre of road before spotting the problem. That extra couple of pints saved me a 650 mile ride home on a tow truck...
