What makes you think it’s assuming it may not be run on the main

macOS does set up several threads, but it doesn’t force any of your
code to run in arbitrary threads.

One of the big TODOs in the NS port is making code that may be called
from lisp safe to run in any thread because at the moment it all
assumes it’s running in a single thread, but lisp can call from any
lisp thread (and then Emacs crashes).
