LGTM, except a small note:
e2e test is good but the change worth unit-test in tests/cli/test_formatters.py.
The reason is: uni-test is much easier to support than heavy-weight e2e one.
From my point of view, e2e is for testing integration with the server; but if the test can be implemented in unit style without mocking etc. -- let's do it.

I don't want to block you but very appreciate writing unit-test to reduce our tech debt and simplify future maintenance.

@asvetlov I'll address your comment in this PR. thanks!
I initially thought of having a unit test. I added a change and ran unit tests, but non failed. for some reason I thought that there were no unit tests for formatters.

[dalazx]

@asvetlov addressed. sorry again.

[asvetlov]

No problem.
Looks awesome, thank you!
