To be clear, my "category 3" was meant for *everything* that would be 
theoretically compatible but lacks the authorisation to sublicense. The 
"category 4" introduced by David Groom was a hypothetical category that 
did have the sublicensing option but was somehow otherwise incompatible 
with the CT.

The Ordnance Survey Open Data License, for example, explicitly permits 
sublicensing so that one would be ok. Also, NearMap imagery could easily 
be made compatible if NearMap were to say "yeah fine, everyone has the 
right to allow OSMF to sublicence under CC-BY-SA or ODbL".

The change in the CT means that in the early versions, you had to vouch 
for the data you contribute being compatible with any future license 
change. This isn't the case any more, you only have to say that it is 
compatible with the current license and that you have the right to 
authorize OSMF to distribute the data under that license.

This last sentence, when read strictly, rules out the import of plain 
"CC-BY-SA or ODbL" data sets without the sublicensing option.
