It seems quite clear that rust users use hyper but few of them want to work on making it work for a C project like curl, and among existing curl users there is virtually no interest in hyper. The overlap in the Venn diagram of the two universes is not big enough.
I think my usecase of curl is entirely covered by hyper (I just use it for http/s with a small handful of flags); but I also have absolutely no idea what goes on inside curl or how my distro chooses to build it.
Rebuilding curl to use Rust here and there (it still supports rustls and quiche) seems like an interesting undertaking, but yeah, I suspect most curl users don’t build it themselves and have no idea what experimental features it could be built with. Guessing the curl survey has data for that.
Stenberg seems like a cool dude and this seems like an amicable split.
