[TYPO3-core] RFC: Integrate Doctrine2 into TYPO3 CMS

[Christian Kuhn]

Hey.

I think it would be great to get doctrine as persistence layer in the 
core. Maybe only as optional feature for some versions, similar to what 
was done with the caching framework (parallel to the old code).

There are two special parts in current core that should be considered to 
be dropped along the way (with bullet proof migration wizards). They 
could save us tons of headaches.

Without going to deep into details:

* Drop comma separated id list feature and adapt be_user<->be_group and 
fe_user<->fe_group to use real mm.

* Drop 'localization overlay in different table' feature. In the core, 
this is only done for pages<->pages_language_overlay, the code is 
hardcoded at multiple parts throughout the core, so the features 
probably only works for *this* table anyway and is probably not used by 
extensions (at least I know none, and I've also not seen any bug reports 
in this area for a long time).
