It's more for the "onboarding" session that you'd cut half the app out, I could have made that more clear. The idea is that you're looking to sprint to value, to get the user's eyeballs on the most-important part of your service ASAP. Otherwise, they don't stick around to explore and find all the power tools. In normal usage, you should definitely have an easy way to find and use all features, but that's a broader product design question, not an onboarding one.
