Perhaps that example could use more documentation effort ...

... but I don't agree with this at all. We specifically do
not guarantee that replacement via SupportRequestSimplify
will be honored, and I think the same must be true for
SupportRequestInlineInFrom. Otherwise we risk breaking
who-knows-how-many third-party tools, as well as cases
where the optimizer declines to inline (eg, because there
are volatile arguments). Besides, what's the value?
