In my mind a delimiter (e.g. colons, commas, etc.) must only appear once but
whitespace can appear repetitively, even with a mix - e.g. trailing space,
newline and tab where the list is long.

In terms of being conservative with what you send and liberal in what you
receive it would arguably be safest to allow for any combination of
whitespace characters but recommend that servers only ever use a single

Compliance with current practices seems sensible too - declaring existing
working implementations invalid is rarely sensible.
