Emacs generally avoids keyword arguments.

I consider them acceptable only for macros (where the cost of parsing
arguments is acceptable since it's done at compile time) or for
function which both need many optional arguments (so positional
arguments are unwieldy) and whose runtime is significant enough that
parsing keyword arguments is a non-issue (e.g. make-process).

Given that there's only one optional argument here, I'd rather have it
be a &optional one.
