I haven't seen this list so cannot comment.

I am afraid it wouldn't be OK because it requires that all
sub-licenses (including onward sub-licenses) have a specified
attribution statement. That is a restriction on use which means that a
contributor (as licensee) does not have sufficient right to grant all
the rights granted in clause 2.
There's a practical outworking of this: the attribution and licence
structure of OSMF does not appear to require me a user of OSM to add
the specified attribution statement myself, which is a requirement of
the Ordnance Survey Open Data Licence.

Better would be "the right to grant all rights to OSMF". A lot more is
being granted than just a right to sublicense under CC-BY-SA etc.

If I understand you correctly, that's right. Clause 2 appears to
prevent most licensed data from being imported. Recently on this list
(I think) we were pointed at the LWG's minutes where it was decided to
take this approach to avoid various risks to OSMF.
