This will return a new instance on each call, with the same state and params. Not a good value to use as dependant of getParsedPattern.

Please remind me, why are all the selectors in this patch registry selectors, when they all select from the block-editor store? Why can't this unlock( select() ).getReusableBlocks() be a straighforward getReusableBlocks?

Because it's a resolving selector :)

What?
Inside the Pattern block, we use
__experimentalGetParsedPatternto get the pattern blocks. This selector fetches all reusable blocks, even though we can tell from the slug if we need those or not.Why?
Simply mounting pattern blocks in the editor shouldn't trigger all reusable blocks to be fetched from the server.
How?
