Many/Most roads and paths won't have this issue, as they are either
verifiable from an aerial image or by casual observation.

We have the same verifiability problem in areas that are either remote or
lack OSM mappers -- they may be infrequently updated, if at all, and how do
we know if they are there now?

I'm not a big supporter of imports, but if you are going to use them, you
should use and verify all of them, not just some bits. I'm not sure if
there is a key/tag for "unverified", but it might be worth looking at.
