Requiring users to memorize a second keyboard layout is very demanding
Not really. It's a natural learning process as you learn the language. Very easy. If you are truly learning the language (rather than just messing around) you can get to the point where you are comfortable typing most common symbols in a week or two.
I used to touch-type APL back in the day. Even though I don't use APL at all these days, every so often, when I do, I am amazed by how quickly I remember where the various symbols are on the keyboard. Some of it just make sense, for example "iota" is shift-i, "rho" is shift-r, etc.
