Closing as this is a potentially problematic solution. Placing non-existing stuff into the cache (trie generated from a stale snapshot) can have weird consequences if one of the non-existing trie nodes gets generated in a next block, never getting written to disk because it's in the clean cache. We could possibly very carefully handle this cornercase, but seems asking for trouble. |

Alternative implementation for #22667, which in theory does the same thing reusing the read/clean cache, instead of introducing a new mechanism. Needs to be benchmarked / verified though.
