As long as we can't even decide which scenario will be the most usual
one, there's not much point in doing *anything*, as the decision
depends on exactly that.
Anyway, if we assume that the number of plugins in chains will be
approximately the same as the number of plugins in parallel, adding
to the same buffer, what happens if:
* all plugins provide only run_adding()?
* all plugins provide only run()?
(Did anyone notice that run_adding() is not far from being
inherently inplace broken...? That's what Kai's examples show.)
