This may be fine as an implementation, but I'm hoping that you aren't
advocating it as a statement or requirement in the spec(?).

As a counter-example, Subversion doesn't use workspaces, but it does the
above aggregation/management of working resources as part of an activity.
SVN administration will list all the "open" activities and when they were
last touched. Since activities are supposed to be transient within SVN
(lasting only as long enough for the client to shove stuff across the
network), it will be easy for the admin to detect "lost" activities and
delete them from the server (along with their associated working resources).
