Hi Niklas,

Thank you for the review.

Yes, it will. I was, however, still wondering where to move it to. I
want to keep init(), start(), and stop() as required IPA functions, but
there doesn't seem to be a place to mandate that technically, since mojo
(the language) doesn't support interface inheritance. I suppose I could
spit out an error at the code generation stage if these functions don't
exist. (Technically correctly we should intervene at the parsing stage,
but we don't want to touch mojo code since that would ruin ease of
updating)

The other functions will become pipeline-specific, so I would move the
documentation to their mojom interface definition files... which means
if a lot of pipelines use the same interface (as they do now), they'd
all duplicate the interface documentation.
