We can explicitly decode and check during add and perhaps e.g. commit.
But having added them, why should we decode them all the time?

I think that paths are inherently unicode and we should treat them as
such. However, we should not store nor process the stored for using
python unicode strings, and this should be purely a performance
consideration, not a semantic change.
