Yeah, this pretty much summarizes my experience. In most situations, the actual information I need to share between different contexts is quite small, and using a channel ends up being pretty clean. There are still times I need an actual reference counted wrapper around a mutex, but they're the exception rather than the norm, and even then, there are often ways you can reduce the contention (e.g. if `T` is a type you can clone, and you only need a snapshot of the current state of the data rather than preventing changes while processing based on that snapshot, you can just clone it, drop the mutex guard, and then proceed without needing to worry about borrows).
