While I'd like to have it, it doesn't stop me from writing a great deal of production code without those niceties.

When it came time for me to undo all the async-trait library hack stuff I wrote after the feature landed in stable, I realized I wasn't really held back by not having it.

Async closures landed in stable recently and have been a nice QoL improvement, although I had gotten used to working around their absence well enough previously that they haven’t been revolutionary yet from the like “enabling new architectural patterns” perspective or anything like that.

I very rarely have to care about future pinning, mostly just to call the pin macro when working with streams sometimes.
