Yes it makes sense in a pagelist. And I don't wish to change this.

Never. And that was my intention.

It is useful for the page posting permission check because by default
it needs explicit permissions being set, i.e. inclusive patterns need
to be added. If none are added then no permission will be given.

It is just the opposite from what one wants from pagelist behaviour.
Or to paraphrase your last question:
Why would a pagelist which always returns every page be useful?
I mean it is just as useful as giving no key means you can't open any
doors, but giving one key means you can open some door. ;-)

Just that the initial default condition should be "No posting
permissions", in the same way as (:pagelist:) is "All pages"
