Deprecated Abseil types ie.(`Breakdown`) in use

[teadetime]

It appears that pybind11_abseil uses deprecated types. ie. Breakdown, From_Datetime. Will/when will this be updated?

These issues seem to appear even when using the 20230802.0 tag of abseil-cpp as specified in the WORKSPACE file.

For a more complete example of the deprecated features see a failed build:

I'm aware of this from working on the code in Apr/May this year, but it'll be a ~3 day project to change the implementation: currently I have to do this in two places, here, and internal absl/python code. Therefore it's way down the list of priorities.

If you like to help changing the implementation just here, I'll look at a PR here quickly. I think we can go through all review and test steps here as usual, only at the end I have to manually import into the Google codebase, from where it will then get auto-exported. A little cumbersome but not a lot of work, and it'll preserve the original author attribution.
