I think this is the way to go, too. I think the normal content rendering
shouldn't be changed for now. But in extensions it would definitely help
to tag rendered records in the pages cache (or pagesection) and delete
the cache selectively when changing records in the frontend.

We have the experience in a community framework that the current caching
solution from TYPO3 is very problematic.

So, how would the cache tagging for page rendering work? I think there
should be a function in the TSFE or somewhere, that adds cache tags for
the current rendering. So when a page gets rendered, the tags from
extensions are included in the pages cache and can be cleared later on.

IMHO smart caching by the framework is something everyone wants but
that's clearly not a short term goal. And better give the developer a
good API and tools to work with the cache now then try to guess what an
extension could want (as someone said, after all we mustn't think in
CRUD examples!).
