Hi Vincent,
while I see your point, and I agree that gpkg could be a good candidate,
I think there are two major issues in choosing a standard format:
* the need to import/export data will put an additional burden on users,
and will result in duplicate and possibly misaligned data
* users of DBs (and we support a nice variety of them) will not have a
choice of moving to "our" format, so they will be put on a disadvantage
compared to standard format users.
All the best.
