With respect to the automated GeoBase import I did a few years back (of
which that is a sample of) I can provide .osm files with all the excluded
data to anyone that asks. At one point I had them up on a free filesharing
site but I think that went away. I don't think Potlach can read these files
though. If someone wants to setup a server that can server them up as WMS
I'd be happy to provide the files as well.
I doubt people doing manual/semi manual canvec imports people any listings
of what wasn't imported (I know I don't keep track of that).
