The only place (... ...) is needed is in macro-defining macros, which

In my opinion it would therefore be annoying to the specify the ellipsis
in the "boiler plate" every time I need to define a standard macro.
Furthermore with-syntax lets you choose your own ellipsis, when
you need to define a macro-defining macro:
(with-syntax ((::: #'(... ...))
<use ::: here>)
I think it's a little nicer to write something like
(parametrized-syntax-case stx *** ()
((syntax-case name vars body ***)
#`(parametrized-syntax-case #,(datum->syntax stx '...)
vars body ***))))))
Disclaimer: I don't know syntax-case well enough to be certain of the
above code, but I think it should be about right.
