I went ahead and committed these patches. I know there's some debate
over whether we want to show the # of disabled nodes and if so whether
it should be controlled by COSTS, and I suspect I haven't completely
allayed David's concerns about the initial_cost_XXX functions although
I think that I did the right thing. But, I don't have the impression
that anyone is desperately opposed to the basic concept, so I think it
makes sense to put these into the tree and see what happens. We have
quite a bit of time left in this release cycle to uncover bugs, hear
from users or other developers, etc. about what problems there may be
with this. If we end up deciding to reverse course or need to fix a
bunch of stuff, so be it, but let's see what the feedback is.
