Isn't that largely the point of the Material action menu, so you have a thing in the lower right corner (near the usual resting position of your thumb), that either does the new or add function, or spills out frequent actions used in that app?
But you're right, of course. There are more and more action menues in the bottom right. But take a typical Apple app like Mail.app. In the bottom right there is only one action: write a new mail. The next step, after clicking it, is entering some information that in many cases will involve clicking something in the header field in the top third of the screen. Even send is at the very top right corner. Oh, the thumb movements...
What pisses me off isn't specific cases like yours, what pisses me off is app developers don't ask themselves, in general, if what they're doing in the UX makes legitimate sense.
As in, eat your goddamned dog food, people.
