Can some of this be changed to use StringView later?

What part? findHTTPHeaderName() already takes a Stringview:
Source/WebCore/platform/network/create-http-header-name-table:bool findHTTPHeaderName(StringView stringView, HTTPHeaderName& headerName)

For example, setHTTPHeaderField and addHTTPHeaderField. It requires making arguments into String if they aren’t known HTTP header names, but do those String objects get kept around? It’s good we don’t do it with string literals, but what about other sources of strings? And what about the value? Does it get stored as a String or some other way? I think there are still extra String involved in those functions.
