The only place (... ...) is needed is in macro-defining macros, which aren't too common. A search through the PLT code base for (... ...) versus a search for ... gives a good impression of how uncommon it is. 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 (define-syntax syntax-case (syntax-case-macro (lambda (stx) (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.
