A class has to setup a layout and it rather difficult how it should do it without defining a default layout. The default for article is letter, and so you should specify a4paper if don't want it -- better for the margins anyway.

Only answering now (I'm not subscribed to tex-live, and wasn't cc'ed your message, hence only saw it when browsing the list archive on the web page):

By neutral I meant set \paperheight etc. to their default LaTeX value of course, but don't attempt to match \(pdf)pageheight etc. to them unless the user specifies [a4paper] or [letter] explicitly : just let these be whatever the driver config files specify, irrespective of \paperheight etc.

But David in the next message explained why he thinks this is faulty design, and instead willingly ensures that \pageheight and \paperheight match. I can identify to that.
