Defining default rendering for certain constructs such as that the <body>
element has a default margin of 8px (iirc) is important for
interoperability reasons and for new UAs trying to enter the market (saves
them reverse engineering other UAs). A lot of web pages rely on default
rendering of elements. For instance, that an element such as <p> has a
default style of "display:block" as opposed to "display:none".
It is very important that UAs falling within the same conformance class
agree on these basic principles so authoring against those UAs becomes
more predictable and that developing a new UA doesn't involve as much
reverse engineering as it used to.
