C++ heavy apps on Android are larger, use more memory, and load less quickly. This isn't obvious if you're used to other worlds, but it is a side effect of how pervasive Dalvik is on the system.

Citation required, as this is entirely the opposite of every experience I've had actually building apps that use significant native code. What are you basing this claim on?

There really isn't anything magical about Dalvik (or ART) -- it is a per instance runtime. C++ code doesn't suddenly become heavier or slower to load because of Dalvik.

And of course the overwhelming majority of games are mostly built using the NDK.
