Ok, so from what I gather, the only change should be:
return Index(items, name=index.name, tupleize_cols=False)
(in internals._transform_index()). If that's agreed, I can make the change
on the other side of the weekend.

I don't think that adding a new keyword to rename is the right level for
the fix. The original example in the issue is a bug. We should fix the bug,
not add a keyword to work around it.
I'd prefer a proper fix for #17246
<#17246> (Index(...,
dtype='object') is respected). Then to fix this bug, we'd pass through
self.index.dtype I think.

In case of a MultiIndex, only rename labels in the specified
level.
+ tupleize_cols : boolean, default False
I'd prefer not to add a new keyword argument here. I don't think that
.rename should be able to change between Index and MultiIndex, so it
shouldn't be necessary.

git diff upstream/master -u -- "*.py" | flake8 --diffNOTE: for renaming, the keyword argument default is False, because as suggested here, this is unintuitive and unexepected. The keyword argument for the _transform_index() is True however, which is consistent with default pandas.Index() creation behaviour.
