In the spirit of good pedantic fun, I'll point out that en dashes are no less inconvenient than em dashes for the average Windows user to insert. The hyphen-minus immediately accessible on the keyboard was (and is) used for the common typewriting kludge attested in Garner's[1] as well as the LaTeX-syntax triple-hyphen em dash (which, might I add, for lack of a better place to do so, isn't one of the ways I've seen dashes used by LLMs or disguised by their operators).
