It is indeed better than `org-sort-function-downcase'.
`compare-strings' with upcase conversion under the hood may be an
alternative.
I would consider a setter function for `org-sort-function' to avoid
branches based of `func-arity' in `org-string<'.
Setter is not reliable when setq is used, so I prefer arity check.
I bothers me as well. Another idea is to require 2 optional argument and
thus wrappers for 2 argument functions. My expectation that extra
function call still may be cheaper.
