One of problems with columnar/ortholinear/split keyboards is that all of them are 40%-50%ish. I never seen such keyboard with '[' and ']' keys in standard places. Sometimes there's no "'" too. Yes, this is by design, because these keys are too far away from home position, but I use Russian layout and it has 'х', 'ъ' and 'э' letters on these keys. Not the most frequent letters but still I don't like idea to have letters on some unrelated places on "punctuation layer". Not everybody likes heavy use of modifier keys. Despite using computers from early 90s I still struggle with pressing ctrl/alt/super before alphanum key, sometimes I press keys in wrong order (i.e. I press alphanum before ctrl is fully pressed). Using multiple layers with Fn keys would be probably a nightmare for me.
