this is not good.  Since GTA01 is already deployed, I think it will
generate a nightmare for updating and compatibility.  GTA01 partition
tables have to be as-is.

I don't think this is acceptable.  People bought GTA01 in the
expectation that we would once finish the software stack for it.  If OM
doesn't deliver a working phone software stack to them, they will feel
tricked into buying a device based on wrong pretext/suggestions.  It
sends a really bad message to the community.

So for the time being, I'd think it is not acceptable to drop GTA01
support from anything.  All features (unless hardware like
wifi/accelerometer/... is required) have to be en par on both units.
Also, there is no technical reason why they'd not be.
