Yeah, "today". That's why I said "If/when". If we do start doing
that, does that make things more complicated in a way we may wish to
think about _now_ while we're designing today's solution?

I'd like to think that we can just ignore it for now and adapt as
things change in the future, but we're all familiar with the way
that everything is way more connected and twisted up in a scary
hairy ball in nova than we'd all like.
