@lmazuel I am constantly amazed by Python. This is technically a "breaking" change because we are changing object types for different return values, but because the tests already didn't try to validate fields that didn't exist and python doesn't really care about types, all my tests continue to pass!

[begoldsm]

@lmazuel I assume that I need to update the versions for the ADL packages manually before committing this, right?

[lmazuel]

@begoldsm yes please! version and Changelog :)

I am closing this PR as I am working with @ro-joowan to manually generate an aggregated ADL python SDK update.
