It actually kind of making some differences in my codebase, and I'm confused about it. I feel like when I don't use await, and then I.say(...) is kind of occupies a small block of time, which potentially hide some smelly code, like, when I don't use await, some of the code runs fine, but when I start using await I.say(...), some bits start broken, because the element the test checks is not ready, I have to add I.waitForElement(...) to make the tests working again.

Another difference is that when I don't use await I.say(...), I seldom see UnhandledPromiseRejectionWarning when I run all the tests, but once I add await to all I.say(...) in my codebase, those improperly implemented async methods start giving me UnhandledPromiseRejectionWarning and it actually blocks some of my workers from running the rest of the tests.
