Browsers already do that. KDE doesn't use x-scheme-handler for browsers at all. Instead, it has a Default Components setting (very similar to GNOME 2's Preferred Applications) where, for the browser, you can set it up to use the program associated with the text/html file type (the default setting) or to use a specific browser. (In fact, this was added in KDE 4, modeled on the GNOME 2 dialog. In KDE 3, it was hardcoded to always use the text/html file association as a browser.) In Fedora, the default text/html handler for KDE is set in /usr/share/kde-settings/kde-profile/default/share/applications/defaults.list with the following line: text/html=kde4-konqueror.desktop; We patch the startkde script to set XDG_DATA_DIRS so this setting is also seen by non-KDE applications. None of the browser packages I have installed override this setting. If I want to change it, I have to either change the priorities for text/html in the file associations or force a default browser in Default Components in KDE's System Settings (or both). See line 286 of: http://quickgit.kde.org/?p=kdelibs.git&a=blob&h=c86a77b02f5bbcc3f357042afb6c6d1cb4bdcb2a&hb=e737ed00d8782d82559d8a9ef9d3bef56ced0b49&f=kdecore/kernel/ktoolinvocation_x11.cpp for how this is implemented in KDE. (You'll notice that, when not running the KDE Plasma Workspace, kdelibs will use xdg-open if installed, so GNOME's way of handling URLs, including x-scheme-handler, will be used in that case.) As of KDE 4.6, KDE now supports x-scheme-handler for the things KDE's old protocol handler scheme is used for, but that isn't quite the same thing as what GNOME uses it for.
