In the case of my code above it only runs once on the first query after
parse_request, which is almost definitely the main query.
In any event what I want to know is "Are we in an RSS feed context?" and
is_feed() answers that question for the page as a whole. If we ARE in an RSS
feed then there will only ever be one query, the one that returns the feed
items. This means the question is really whether you want the
category__not_in (or whatever other query var) to affect feed results,
there's no other queries in feed pages that you need to worry about.
