I would suggest that for new trees we just look for an ack from an
existing tree maintainer.

I would suggest a slightly different policy here - given that
maintainers of subtrees may not be fully familiar with the details of
other subtree. However, they should have a reasonable high-level view of
the project. Therefore I suggest:

* the backup maintainer for the master tree should be selected from the
  existing subtree maintainers from the project.
* the backup maintainer for a sub-tree should be selected from among the
  component maintainers within that subtree.

Having things this way would ensure that the maintenance of the master
tree is always done by someone familiar with maintaining trees, while
also at the same time having a way to allow others get familiar with
maintaining trees by taking a stint as backup sub-tree maintainer. It
also should ensure that e.g. the net tree committer is always someone
familiar with NIC PMDs.
