Please bear with me if I'm being stupid — my lack of knowledge of land ownership and permissions is legendary! — but what happens if currently deeded land is simply un-deeded and set to group? What dramatic consequences will happen?
I dislike the idea of 'breaking land apart', taking at away from citizens, and giving it back (even if to the same citizens again), because it's a bad precedent, as Tor has pointed out. However, I remember that ages ago I turned parcels from deeded to merely set and back again (and vice-versa) and no catastrophe occurred. Have things changed?
Besides streaming — which, as said, can be fixed with a special object — what main differences exist between deeded land and land set to group? I mean in the CDS; I'm aware of the 10% tier bonus on the mainland.
Also, I'm reluctant in accepting 'grandfathered deeded land'. If it's more damaging to the CDS, why should we accept that 'grandfathering'? I remember when we stopped having microplots. Many complained that the mini-plots allowed poor citizens to still remain citizens, and now we removed their option of keeping their citizenship, so this was unfair, etc. and microplots ought to be grandfathered... but at the end of the day, we just created a law that allowed a transition phase, but, eventually, microplots were abolished. There are a lot of rules that never get 'grandfathered', and often for good reason.
Mind you, I'm not opposed to grandfathering deeded land in general — if there is a good reason for it, then sure, let's hear it!
That said, I agree with Rosie (sorry, Cindy!) — handling 'group citizens' was a mess when we allowed that, and it's really hard to track down, as membership comes and goes... also, someone who has partial rights to a group, are they citizens or not? You can see how quickly this becomes unmanageable.
And yes, like Bromo said, it would be fair to keep group-owned land to a limit as well. It looks like a good idea to make the group-owned land the same limit as individually owned land.
On the other hand, I'm always happy to hear people worrying so much about all land getting sold Doesn't that mean that we should be worrying about adding more regions? Heh. My expansionist soul rejoices hearing that!
