Some time ago already, after [the feedback topic on concurrency here](https://forums.swift.org/t/swift-concurrency-feedback-wanted/49336) came and went without any news on `reasync` despite the lack of it being mentioned multiple times as a pain point, I started monitoring the situation in order not to miss any new development in that area.

Oh, nothing fancy: [just searching for the term on these forums, by itself, with results sorted by latest post](https://forums.swift.org/search?q=reasync%20order%3Alatest). Then one day, [this result](https://forums.swift.org/t/se-0395-observability/64342/34) showed up, which I'm quoting here for convenience:

> Lest these be dismissed with "ah, but no _true_ future scotsman ever gets implemented" I should note that many future directions are along the lines of "this is maybe a bad idea, but this proposal doesn't rule it out" (personally I put `reasync` in this camp, but there are plenty of less controversial examples), or "this is a future possible direction, but meh" (SE-0268 has one of these) which are unsurprisingly unimplemented.

The context, for what it's worth, being @ben-cohen defending the idea that future directions are _not_ just where proposals go to die.

Since I've been [twice](https://forums.swift.org/t/a-case-study-for-reasync/64590/10) [challenged](https://forums.swift.org/t/a-case-study-for-reasync/64590/22) in this topic to put up as to what I alluded to in the initial post that made me clean up, elaborate on, and post this study, I am bringing this to everyone's attention so as to answer this challenge.
