I don't think that the answer to this question is a blocking one [1]
with regards to Windows.

I believe on Windows, everything is "inherit" from the parent dir by
default anyway - regarding permissions when creating subdirs and files.
As long as we don't interfere with that, we should be fine on Windows.

So I think we can safely ignore Windows for now while pondering Matt's
proposal.
