ActiveModel lint test, #attributes and []

Is the AMo lint test up to date?

I'm writing a new-feature patch and I need #attributes and [] (that
is, my_object["foo_attribute"] to be defined, but I don't see them in
the lint test. Seems like the lint test is rather short, is that all
it takes to be an AMo instance?

Thanx!

Forget []. I do need to know if #attributes is available on an
ActiveModel instance.
