Once somebody brought the idea in typo3.dev I suggested to implement
this as a TCA feature (ie a flag that says that this table has along the
pid also fields for a nested set). There was little interest

But you point out the one major flaw of nested sets and the page table.
Mount points and nested sets don't go well together. Maybe the recursion
required for mount points can be delegated to a stored procedure :-)

And this made you understand it? Amazing.
