BSON's specification is also a little less generic (& tied to its
origins) than I'd like. Two small examples: having a concept of what a

there's things like 'timestamp' - which the specification notes is a
"special internal type used by mongodb replication and sharding".
Things like that are, in my opinion, not that great.
