Thanks, your Redis story sounds exactly like my motivation. When the cache layer becomes the primary persistence and you’re pushing around millions of JSON-encoded Pydantic objects, the overhead hits both RAM and the bill very quickly. That pain is real.

Regarding getting this into Pydantic core: I doubt the maintainers would want to ship and maintain a binary serialization layer inside the main project. That said, it might still be worth opening an issue to hear their perspective - worst case, it becomes a documented "won’t include".

As for continuity and lock-in concerns - my primary production workload depends on this library, so I fully intend to keep it updated alongside new Pydantic and Python releases. I also intentionally designed it with minimal dependencies: core functionality uses only pydantic and typing-extensions. The only extra is leb128, and that’s just for UInt128, which almost nobody truly needs - I’m considering moving that to an optional extra to keep the base install even leaner.
