It's definitely a tradeoff. In my experience, it's well worth it. For messaging, I use a union of the possible message schemas. I wrote a library (https://github.com/deercreeklabs/capsule) that makes messaging (events and RPC) simple and easy. It uses Lancaster / Avro over WebSockets. Unfortunately, it is not yet documented for public use. I hope to get to that early in the new year.
For persisting data in storage, I store the fingerprint64 of the schema along with the data, then have a lookup table of fingerprint64 to schemas. Again, this works very well for me. Your mileage may vary. Avro's compact size and Lancaster's speed make it very nice for messaging and data storage. I also value having the data types validated at serialization time. I love dynamic typing, but believe that types should be checked at boundaries (messaging, storage, etc.). Lancaster makes it easy to do that.
