Investigate: Determine if breaking changes reduce ability to use nomadic identity
When discussing whisperspace, we figured that it would be easy enough to add a new field to a post, but that will require DB changes and we don't know the effects of making DB changes on our users' ability to go to Hubzilla core instances.
We need to figure this out before we make any such changes, so that we can at least make an educated decision about whether to make them. :)
