So let me get this straight. You want the benefit of being able to re-use other peoples' codebase by using an HTTP crate you didn't write. But you don't want those people to also use that benefit of depending on other crates.

Insisting that you should depend on code which itself has no dependencies is a bit hypocritical if you ask me. If you want a simple HTTP crate that doesn't have dependencies, you should follow your own philosophy of not using other crates and write it yourself.
