AOB	All	Notes below.

Serializers

• Stu's POC proves that we can make gzip work with JS6
  • What is the meaning of max message size? Bytes over wire? JSON size? Is it UTF8? Seems to be Encoding.UTF8.GetBytes
  • Let's work out exactly how this calculation is made
    • Client uses headers + body, UTF8 encoded
  • We could provide a nuget package with an alternative compressing serializer factory to allow users to opt-in
    • Need to investigate whether gzip'd messages are dropped or move to _error queue if consumer can't handle them
  • Can we support cloud event envelopes? What wold be necessary?
    • Worth investigating if we can support multiple envelopes?
    • Potentially easy, likely difficult, worth investigating.
