i'd love having a per compute/storage resource 'behavior' toggle would, that'd be cool and
flexible. say i add storage to a cluster i can mark it 'tag required', to not allow tagless
offerings to deploy there.

Did you discuss the case where a resource offers A,B but the requirement is for only A?  
Would that fail to match?

The current design is just that the offering tags are requirements (and an offering with no
tags has no requirements).   That does force everything to be tagged to get "negative" control,
but it seems relatively easy to think about.
