Hi Pierre-Olivier Roy!

KDevelop is built against Qt WebEngine by default. Qt WebEngine is 
included in all recent Qt versions. Only if Qt WebEngine is missing, 
KDevelop falls back to the alternative Qt WebKit dependency.

KDevelop uses Qt Web(Engine|Kit) for code documentation (Documentation 
tool view), not for the User Manual.

And yes, many distributions package Qt WebKit built from 
https://github.com/qtwebkit/qtwebkit against their Qt versions. For 
example: 
https://github.com/archlinux/svntogit-packages/blob/packages/qt5-webkit/trunk/PKGBUILD

Cheers,
Igor
