We're no longer planning to implement this improvement as part of the SBE plan cache project, for a few reasons:
- The classic plan cache had similar behavior around cache invalidation when catalog entries occur, so we won't regress. We also don't necessarily have a strong motivation to improve this behavior as part of building the SBE plan cache.
- We're unlikely to have time for it given our current schedule.
- We don't currently have a design for how this will work. It's unclear how the new plan cache invalidation behavior would interact with the cache key versioning scheme that we introduced under
SERVER-60066.
