I think a SliceHelper class like this is a reasonable solution, but there would be a lot of value having it a standard place somewhere in the standard library (e.g., operator.subscript).
Both pandas and NumPy include this helper object under different names (pandas.IndexSlice and numpy.index_exp / numpy.s_), but it would be surprising/unexpected for pandas/numpy specific helpers to show up when
not
using one of those libraries. I do the exact same sorts of indexing manipulations with xarray, dask and TensorFlow.
Given that this is basically a simple feature to make it easier to work with Python syntax (so there's no danger it will change in the future), I think there is a lot to be said for putting it in the standard library in one place so it's obvious what to use and users don't have to relearn
that
name for this object and/or reimplement it.
Please copy that comment into the ticket and ask for it to be reopened.

I basically did exactly that last week! See https://bugs.python.org/issue24379#msg321966
I was told, "You may get more traction on python-ideas" :)
