I'm sad that anything I said made it sound like I thought crypto wasn't very very hard or that it's reasonable to assume a particular new crypto algorithm works.
My bottom line is that the stated goal of MTProto is UX (perf) and both signal and WhatsApp have worse UX than telegram. I would like security people to consider that maybe telegram did what they did for this reason (their stated reason!) and maybe the status quo has problems.

I use telegram and signal. I don't use WhatsApp because it's unusable for me. Security analyses that ignore UX considerations result, at the limit, in recommendations that people adopt PGP.
