The lack of a stacktrace alone should be a hard blocker to microservice migration.

After that, the amount of cpu (i.e. dollars) and wall time wasted on encode-decode.

Anyone who does a microservice migration is not accounting for the above two costs.

Or maybe they are, and they still think its worth it? Stack traces are not an issue I've faced, good tracing helps a lot here. Encode-decode is a minor issue in comparison to the issues they are often trying to solve (which may not always be technical, especially at larger orgs)
