    I noticed that there is currently no support yet in the from_dataframe function for boolean columns with bitsize 1. Is there an issue for implementing this?

    import polars as pl
import pyarrow as pa
import pyarrow.interchange

df = pl.Series("a", [True, False], dtype=pl.Boolean).to_frame()
dfi = df.__dataframe__()
pa.interchange.from_dataframe(dfi)
# NotImplementedError: Conversion for (<DtypeKind.BOOL: 20>, 1, 'b', '=') is not yet supported.

    No, there is no issue - I think we missed it as we didn't have the use case then.
    Will open a new issue to implement it, thanks!
