On mobile platforms it might be a sensible optimization to package web-inspector separately from QtWebkit package into its own package (debian package, sis file, etc), so that the inspector would not get installed into all production devices; instead it would be a developer add-on. For Symbian http://trac.webkit.org/changeset/47635 disabled Web-inpector, so one would need to rebuild QtWebKit just to get inspector working again. This setup is suboptimal. Qt's External Binary resource feature could come handy here (qrc, rcc, QResource API can be used to register with Qt application).
