Comment (by joemcgill):

 Thanks @flixos90. I agree that we should consider both strategies together
 here:

 1. Caching the merged data non-persistently to eliminate the need to
 recreate the merged dataset multiple times per page load
 ([https://github.com/WordPress/wordpress-
 develop/pull/5024#issuecomment-1724558515 PR #5024])
 2. Persistently caching each theme data origin (core, blocks, theme, user)
 based on the different invalidation rules needed by each
 ([https://github.com/WordPress/wordpress-develop/pull/5267 PR 5267])

 Could you take a look at the initial PR and provide feedback from your
 testing? I'll do the same with yours.
