since we do our own synchronization of these variables we can turn off isolation checking. of course that means the responsibility is on us to make sure everything is correct, but luckily all of this goes away somewhat soon!

The Actor.assumeIsolated function is supposed to be back deployed to iOS 13, and that does seem to be the case locally, but CI says iOS 17+. If we can figure out CI we can get rid of this.

It was back deployed only in the Xcode 15.3 toolchain with Swift 5.10 AFAICT, not in 5.9 yet.

Ahhh ok, so I can work around that with some #ifs. Thanks @pyrtsa!
The majority of sendability problems in TCA right now is in APIs that will be deleted in 2.0, but there are a few very simple warnings we can fix right now just to be a little proactive.
