I would argue that supporting whatever the programmer's chosen mental model is
actually Swift's greatest strength. We could have a language with only
reference types for example, it would be far, far simpler and easier to teach.
I am glad that we don't have that language.
We kinda do, though, or did, in Objective-C (well, the “Objective” parts of it,
anyway).

Exactly. I mean the same people who brought us ObjC decided we needed a
language with multiple mental models. They could have shipped reference types
only, they shipped value types on day 1. To me there is no clearer plank in
the platform than that.
If you like your ObjC, you can keep it. Swift exists exactly because we reject
some (not all) of the ObjC way, and it's not just syntax. One of the things
rejected is There Should Be One Way To Do It™. Swift embraces many ways to
write your program and has from 1.0.
