An API is needed to control QML imports, this allows for applications to use it as a scripting environment without windows popping up, or as part of platform security on platforms which provide a QML entry point.
-should allow redirects for attempts at restricted use
-should work even on ‘builtin’ modules
-should not be applied in a default QQmlApplicationEngine, but be configurable on the engine

This session aims to fill out the above list of requirements and decide on the API.

Decision is that we’ll try to stick with the new QQmlAbstractUrlInterceptor. By redirecting the attempt to load the qmldir, to fallback implementation or to an invalid implementation (preferably with a qmlError() as well). Custom control can be added to a QQmlApplicationEngine at the C++ level fufilling most of the above needs (with the exception of being able to restrict built-in imports such as QtQml 2.0).

One thing that might help would be to see if the current file or context could be made available to the QQmlAbstractUrlInterceptor.
