V8 uses an incremental collector (somehow?), which I've been

Google agree.
Clearly others have already had this quarrel, their

consideration.
An interesting thing to note, Apple tried garbage collection
with Obj-C, but only on MacOS, and it's now been deprecated
since automatic reference counting was introduced [1]. It
never was on iOS.
So that is a telling omission I think.

The main reason was that the GC never worked properly given the C
underpinnings of Objective-C.
Too many libraries failed to work properly with GC enabled, plus
you needed to fill your code with GC friendly annotations.
So I imagine Apple tried to find a compromises that would work
better in a language with C "safety".
Even that is only supported at the Objective-C language level and
it requires both compiler support and that objects inherit from
NSObject as top most class, as far as I am aware.
Anyway it is way better than pure manual memory management.
