cc @simonjayhawkins there are some failures on numpy dev build, like:

________ ERROR collecting pandas/tests/frame/indexing/test_indexing.py _________
pandas/tests/frame/indexing/test_indexing.py:31: in <module>
    class TestDataFrameIndexing:
pandas/tests/frame/indexing/test_indexing.py:80: in TestDataFrameIndexing

    mgr = init_dict(data, index, columns, dtype=dtype)

pandas/core/dtypes/cast.py:1440: in construct_1d_arraylike_from_scalar
    dtype = dtype.dtype
E   AttributeError: type object 'object' has no attribute 'dtype'

Did you already see that before?

But merging this, since it is unrelated to the whatsnew

Did you already see that before?

no, but I think should soon have a fix. This is not present on master, mainly down to the changes in #33725.

rather than try and backport all the changes in #33725, will raise a PR shortly with just the changes to fix CI on 1.0.x branch directly against the 1.0.x branch.
