I'm not trying to present the point of view of me as the author of LDView. I'm trying to present the point of view of users (and in particular, non-expert users). From the point of view of a majority of users, "MPD" is just some esoteric jargon that only programmers understand. All the programs they use to open LDraw files can open both "MPD" and "LDR" files.
And MLCad suggesting MPD as the extension is consistent with what I said: originally it was good to use the MPD extension due to lack of support in other programs.
