For what it's worth Malcolm I largely agree with you.
On my Ulster rep it is possible - just - to winch the engine in and out with a deep sump on; it works better if you do it with the flywheel cover off, the head off, and the rear two head studs removed. It is lowered in with the gearbox tilted down and then rotated level by means of a bit of rope slung around the gearbox. Of course feasibility will differ car by car.
The sump can be removed in situ but this largely depends what you have stuck it to the case with as it's difficult to exert much downward force. It may be necessary to jack the front up ever so slightly to clear the chassis rails.
Likewise on oil temperature - I measured it once on a winter's day country lane run and it never got above 65 C. On the other hand no particular harm seems to have resulted in touring use. One solution which has been put forward is simply to fill it to the same capacity as a standard sump (the effectiveness of the aluminium fins I would venture is trivial).
The man reason to use one is (a) higher stiffness - whilst the semi-deep is stiffened I doubt it lends quite so much rigidity to the case as a deep one; and (b) the added capacity, which has proven useful more than once on a long, high speed run. I can darn near empty a sump on a run up the A1 to Newcastle!
