• Update RawValue.Binary(OK) to return bson.Binary
• Update RawValue.DateTime(OK) to return bson.DateTime
• Update RawValue.Regex(OK) to return bson.Regex
• Update RawValue.DBPointer(OK) to return bson.DBPointer

• Update RawValue.Symbol(OK) to return bson.Symbol
• Update RawValue.CodeWithScope(OK) to return bson.CodeWithScope
• Update RawValue.Timestamp(OK) to return bson.Timestamp
• Consider deprecating or removing RawValue.Time. Suggest using RawValue.DateTime().Time() instead.
  • That's not quite as convenient for the OK use case, so maybe keep it?
  • Should we replace it with AsTime(OK) instead?
• Consider deprecating the BSON library types and methods that correspond to deprecated BSON types
  • Undefined, DBPointer, Symbol, CodeWithScope
