It has been on Swift and Apple's official documentation since the early days.
People keep forgetting that Objective-C also had a full stack role on NeXTSTEP.
And the same full stack approach was also a thing on Xerox PARC systems, which mostly failed due to mismanagement.
Usually ends well for closed source platform vendors when developers aren't allowed to come up with alternatives like on FOSS operating systems.
At least, as long as the platform stays market relevant.

In terms of Apps and Low Level Stack Objective-C doesn't seems wrong in my book. The problem is Swift begin as a much larger language and evolve into a gigantic pile of a little of everything.
Doesn't seem to hinder C++, which modern C compilers are written with nowadays.
Despite all its complexity, LLVM and GCC aren't getting rewritten any time soon, or the OSes that rather use C++ subsets instead of being stuck with C.
