HTTP libraries in general are tough because HTTP in practice requires understanding of at least DNS and TLS and in a lot of cases L4 networking as well. If you try to target application developers you end up with leaky abstractions (unread H/1 body draining behavior when you don't even know what HTTP version you're using) or a library low level enough that application developers don't know how to use it. See rust's hyper and reqwest as an example of an attempt at that split.
