I think this will only complicate the rules and make contributing
a specialists' game. Every time you complicate the rules, you add
uncertainty, cognitive overhead, opportunities for lengthy discussions,
controversies (for an extreme example, think of the Wikipedia process).
There is enough boilerplate to care about right now when integrating a
patch.

At some point, we should recognize our pain is more important than
others' when it comes to the fitness of *our* community. I don't see
those other people caring about our pain, and proposing e.g. to offload
some of the maintenance burden (for example the 2.7 LTS maintenance
burden, the maintenance of security branches). For some reason it
sounds like we should be altruistic towards people who are not :-)
