I didn't ask whether Emacs has the requisite information, I asked about the use cases for these commands. You presented none; instead, you are lecturing me on basic Unicode attributes of characters and on the reasons for having the wide ones. That is not helpful; I already know all that. It definitely doesn't provide any rationale for having such commands in Emacs.
