In #1041 I proposed we use kstring crate for our strings. kstring::KString is like a Cow<'static, str> with small-string optimization. This removes lifetimes from our types but more relevant to here, offers us more Into flexibility that makes it so we can trivial implement the API we want (see #2857 for some of the problems).
