How to handle beta vs non-beta streaming shapes without duplicating code?

[akosyakov]

I'm using both standard features and beta features in my Go app. The streaming event shapes are completely different between non-beta and beta streaming, which means I need to implement streaming logic twice. Is it safe to just use beta streaming for everything (even without beta headers)? Or what's the recommended pattern to avoid maintaining two separate implementations? How are others handling this?

Do I understand correctly that beta is actually a superset, so it contains stable shapes which are not going to change, and then unstable, and with careful usage it should be possible to use both?

The only difference I noticed in such case is beta query param, but which can be removed via options?

I'm generally surprised how complicated it is to intervene non-beta and beta given on wire it is the same.
