Local account on Win11 isn't a workaround, its a fully supported option but only on Windows 11 Pro. Its a work around on home edition. The UI to get there on Pro isn't intuitive (Other Options->Domain Join Instead->Create local account), but it's there and 100% supported.
Still unacceptable for home edition users, but Microsoft has been segregating its userbase and features into Home/Pro/Enterprise for decades.
