Hi,
Thanks for this PR,
Any chance to rebase to trigger CI/CD ?

TBH I don't like this implementation.
It does not support different adapters for different use cases.
It should be possible to register specific adapters for the protocol.
Plus, the methods here should be renamed to not clash w/ core methods (existing or new to come).

There are two approaches used in core Odoo to support adapter/plugin like features:

1. Adapter specific logic guarded by an "if" statement in extension methods.
2. Base method routes to adapter specific logic using dynamic calls to methods.

The 1. approach has some limitations; the 2. approach is the de facto standard, as seen in delivery carriers and , payment providers.

I can work on expanding this idea to include the routing mechanism.
