LGTM. Some comments.

train_batch = train_batch.as_multi_agent()
self._counters[NUM_AGENT_STEPS_SAMPLED] += train_batch.agent_steps()
self._counters[NUM_ENV_STEPS_SAMPLED] += train_batch.env_steps()

Is this one not using the MetricsLogger, yet? I use it in my overhaul of offline RL

Yes, you should. All good there. :)

But the hybrid API stack still goes through the summarize_episodes utility inside algorithm.py, which operates on the old RolloutMetrics objects returned by RolloutWorkers.

Here, SA=single-agent and MA=multi-agent.

Note that the BC Algorithm - by default - runs on the hybrid API stack, using RLModules,
but not EnvRunners or ConnectorV2s yet.

Can we give a quick note, why in this case the user needs to provide the spaces?
