A question, is this database only intended for very large polygons, or
also rather small?
From my mapping perspective here in Sweden fuzzy polygons exist down to
say ~1 km size (generally speaking names of hills, valleys, peninsulas
etc). In fact the most I run into is in the 2 - 10 km size. I also come
across many bays and straits of similar sizes, those can be defined (and
rendered) in OSM already today, but I now understand that many don't
like that they exist, so maybe those should be managed in this type of
separate database too?

In short: technically CC0 may be used, but it would be confusing as ODBL would still
apply anyway.
See https://wiki.osmfoundation.org/wiki/Licence/Licence_Compatibility#CC0
"CC0 licenced material is in general compatible, however the license only extends
to material the licensor actually has rights in and specifically avoids making a
statement on the status of any third party material included."
So you could license this as CC0, but it does not mean that other limitations are
not applying (limited extraction of just some shapes from OpenStreetMap may
be doable without triggering ODBL - see
https://wiki.osmfoundation.org/wiki/Licence/Community_Guidelines/Substantial_-_Guideline
but such project would likely quickly pass it).
For the avoidance of doubt, there is currently no data from OpenStreetMap in OpenGeographyRegions, and there will not be in the future, so that the data can be used without limitations. My intention is using it together with OSM data, but of course you can use it with whichever data you want.
These regions, although it would be legally possible, should not be imported in OSM either, because they are in medium and large scale resolution and not suitable by their nature (not well defined on small scales, fuzzy boundaries, etc.).
Cheers
Martin
