It also largely sidesteps the issue of whether a particular feature is or isn't a street, which isn't always obvious. Can you elaborate on using it with parentstreet rather than street. I guess this is about avoiding housenumber being put with street by unaware apps and so probably a good idea, but on the negative side we'll not be using any recognisable tags above locality for these apps.

I really don't like the idea of addr:substeet. I don't think this
helps too much with the problem of assigning streets to non-street
objects -- If an object isn't a "street" then surely it's not a
"substreet" either. I think having three different addr:*street tags
when you only ever use two at once would likely lead to more
confusion. (We can't avoid having addr:parentstreet if we want to
maintain the fundamental concept that addr:housenumber numbers within
addr:street when addr:street is present.) So is there really a need
for an additional addr:substreet tag? What does it give you that you
couldn't use addr:street for?
