Do we even need a breaking change at the moment? This doesn't really add anything (eg: why would a user want to upgrade) vs just removing obsolete functions which could occur later when we have another reason to release a breaking change.

Can we instead do a normal feature release to add those couple things you needed?

We did a breaking change last time we removed deprecated code and altered supported .NET versions: https://github.com/EasyPost/easypost-csharp/releases/tag/v6.0.0-rc1

Sorry, my question isn't do we need a breaking release for these changes, it's do we need to do any of this now? Can we wait until there is something substantial to include which would be a motivating reason to upgrade? Cleaning up tech debt typically isn't super exciting to end-users who would then choose not to upgrade if not accompanied by other features.

No, there is nothing in this specific PR that is immediately needed.

A separate already-merged PR that changed supported .NET versions should be released given that .NET 9.0 is now officially released, and as previously noted, a major version bump was used to change the .NET versions last time (although that also included code removal; we can discuss using instead a minor release to alter .NET versions).
