Before adding a new feature we should hear more about why you think
it's needed. afaik we haven't needed this capability in the past ten
years or so and may not need it for another ten. Hence we probably
shouldn't add it!

IOW, please explain at some length why you need this. Do you think
that there are existing call sites which can usefully use this feature?
Do you expect that new callers are likely to need this? etcetera.


Patches 1-3 are general cleanups and look good, so I grabbed those.
