The default role of a data table under roles is now a floor: a connection
naming no role also holds the roles its viewer is a tenant of, unless the
default is admin. This replaces the explicit as=viewer option, which is
removed from the reference parser, the executors and both clients. The roles
drawer warns while the default is admin and confirms before removing the
default role.
