Yes it is. This is weird, why doesn't the controller just take the
agent-stream that it was bootstrapped with?

Attribute                    From        Value
agent-metadata-url           default     ""
agent-stream                 default     released
agent-version                model       2.3-rc1.1

My knowledge of how these streams work is limited but I actually just
expect the agent stream to be the same as the snap channel by default. This
seems to be the case for bootstrapping: when you install the candidate snap
and bootstrap a controller, the controller is the same version as the snap.
So naturally, I expect `juju upgrade-juju` to upgrade the controller to the
latest beta release.

Using snap channels to select which release you want is very ease and
common. Every "new dev release" email from the Juju team explains how to
install the dev release using snap channels..
