TYPO3 Core

Right now, the TSFE is being initialized in index_ts.php and the initialization procedure cannot be re-used, i.e. when trying to create a TSFE instance from an eID script. This is especially problematic since an inproperly initialized TSFE may "work" in the sense that there are no obvious errors, but it may be incompletely populated thus causing issues that are hard to track down.

Thus the question is if the a subset of the functionality currently contained in TYPO3\CMS\Frontend\FrontendRequestHandler#handleRequest, i.e. the subset that initializes the TSFE, could be refactored into e.g. TypoScriptFrontendController::createAndInitialize.
