> The class {{OutputTimeFn}} is overkill for a Fn API crossing. There are only three sensible
values known: MIN, MAX, EOW. The interface is right for implementing these, but the full class
is left over from the days when there was little cost to shipping new kinds of fns. An enum
is concise.
> This can be done "mostly" backwards compatibly with legacy adapters in place, but might
be less confusing without them.
