Drummond & all,

TL;DR:  Include Use-cases in comparison?

Longer:

I agree that this Google doc seems like a good way to make a 
comparison between DID structure choices that may have a long-term 
effect. I look forward to seeing the others filled in.

However, in that document shouldn't there be some reference to 
use-cases, since, AFAIK, they are potentially impacted by the choice?

Specifically, how would any proposal make it easier or harder for even 
a single major use-case (like the refugee migration documents) to be 
achieved? Or even better, perhaps three or four representative use-cases?

Or at very least, put a direct mention in the "Rationale" section that 
variable ability to achieve use-cases should be considered and noted?

IMO it's the one thing everything on the list shares; when this DID 
system is up and running, what use-cases will it be able to 
perform...or not perform?
