billiebob, simultaneous localiser and glidslope intercept is not a substandard service - in fact at my airport our largest commercial operator is now asking us to do it like that for all of their flights.
From the point of a radar ATCO (or at least this one!) the shorter the final for a slow(er) aircraft the better. I'm lucky in that for one of our ILS approaches I can descend you below the platform level by a few hundred feet to make sure you're below the glidepath at the FAP (6 miles in this case), but this is not always the case.
