Yes, "|" is an option.

I just started working with the cookie vmod this morning and this would be a useful feature. As I understand it, Varnish 6.4 (we're on 6.5) replaced filter() and filter_except() with keep() and keep_re() and that the previous functions could take CSV strings.

I think there is a misunderstanding here.

We renamed filter_except() to keep() because it had better semantics,
much easier to understand. The filter_re() and keep_re() functions are
regular expression variants for basically the same operations: filtering
some cookies out, or keeping a subset of the cookies.
