Yes, RHEL has never shipped QtWebKit, as far as I know because of support 
(especially with security updates) concerns. (They're likely to also not 
ship QtWebEngine, but that will be a topic for RHEL 8. QtWebEngine did not 
exist yet when RHEL 7 was released.) They also ship kdelibs with 
Plasma::WebView patched out, kdepim without KMail (because it depends on 
QtWebKit), Qt Assistant built against QTextBrowser, and similar such feature 
removals/degradation throughout KDE.

If all that stuff moves to QtWebEngine, we will likely end up with Fedora 
and Debian getting similarly crippled. :-(
