Thanks for the pointers, @encukou! Based on your suggestion, I came up with [an implementation for sys.abi\_info](https://github.com/python/cpython/pull/137476).

For now, I have only added the core three properties, though adding further ones is rather straight-forward.

Regarding the wheel next variants, I think it could be a good idea to align with this by declaring a special namespace, say `builtin`, `interpreter`, or, indeed, `abi_info`, which would allow us to refer to the pieces of abi information as, e.g. `builtin :: pointer_size :: 32` and similar for purposes of packaging.
