* The KDE system for network protocols ist called KIO. KParts is for user interface components. AFAIK, Falkon isn't using KIO because QtWebEngine has no extension points for that (and if it did, somebody would need to write HTTP2 and HTTP3 implementations or Qt wrappers for KIO).

Yeah Falkon is not using KIO. Same for Konqueror for network request. In the old time of QtWebkit and even older time of KHTML, the webview would reuse the Qt network stack, but now it's reusing the implementation from Chromium.

Btw KIO is now using QtNetwork for it's http implementation, instead of having it's own. So http2 is now also supported.
