f-sting mini language has diverged from format's
>>> spam="Spam"
>>> f"{spam=}"
"spam='Spam'"
>>> "{spam=}".format(spam=spam)

I think that would be the primary motivating factor behind recommending
Ellipsis, it’s already a builtin and we are not likely it to get another
builtin singleton. Ever? But besides that “...” in a function signature,
although maybe looking magical, does immediately call out to the reader

Not quite true, we also have Ellipsis, which already has a nice repr that
both reads easily and still follows
