Answering my own question, the namespace seems to be 'subpluginname_mysubplugin' - that is, the name of the subplugin given in subplugins.json - underscore - name of the subplugin. Although, again dissapointingly, I couldn't find this documented anywhere so I still could be wrong.

Followup question.... how do class names work.

That is... if I have a class/file - local/myplugin/subpluginsdir/mysubplugin/classes, what would the namespace and a the name of a class therein look like?

I usually try to work out what the "edit" URL would be for the block. I'm not familiar with that block so can't be much more helpful.
