Oh yes, I feel the new power rising! :D

Yeah, me, too. EnvRunners growing to become adults :D

So, if a user overrides the SingleAgentEnvRunner , she still can pass it into Algorithm.env_runners?

Yes, you can bring your own EnvRunner sub-class as you like.
See e.g. rllib.algorithms.tests.test_worker_failures, which uses sub-classes of SingleAgentEnvRunner and MultiAgentEnvRunner.

Why is this? Imo users using still this "old" form must switch anyways in near future - so they could do it now. It's a small change.

It's mostly for ourselves :|
Some scripts of ours work for both API stacks and we don't want to make the exploration_config dependent on this. I'm fully with you: This is currently very hackish and should be cleaned up. I'll create another PR to see, what the impact would be for our code base (and tests), if we get rid of this hack.
