Originally I was somewhat ambivalent about this issue, but can see 
some situations where manual cache hints might be useful.

For example, there might be a particular pipleline where auto-caching
might conceivably produce "too many" caching-points. One could fine-tune 
this situation by switching off auto mode, and use cache pipeline-hints
selectively. However, I imagine this to be a very rare situation.

Of course "pipeline-hints" is a generic proposal and is independent
of the caching-point context.

When what works? Do you mean after the pipeline-hints works?

Not familair with this, Will need to look this up.
