would there ever be a case when both are present? Do we just want to not allow this and then hydrate -> attach on pre16 versions?

So, I’ve normalized the options here - which means it will end up having both the best time it hits this code path. So altho users really shouldn’t supply both, i cant think of how to differentiate between user options and things passed in via shallow calls or adapter options etc.
