Review Comment:
Also, assuming there's still some future plan to offload expensive stuff
like data scanning to a rust core, I do wonder if we want to commit to exposing
additional scan planning APIs that may not align with whatever query engine
gets embedded in pyiceberg?
In the case that this is primarily intended to be for the benefit of
pyiceberg's own scan execution I would consider making this a private API.
