oh ok so now instead of 1 immutable bit that can be cached forever we have to store an id. Good news, instead of a wonderfully compressable bitmap you now have

oh ok so now instead of 1 immutable bit that can be cached forever we have to store an id. Good news, instead of a wonderfully compressable bitmap you now have a bunch of uncompressable 128bit nullable uuids. Only a few thousand times less efficient! Oh and of course you now have a linked list structure you have to traverse every time you want to resolve a tweet. Cool. It's almost like this is hard.
