How would focus passing affect this? You have to click on the
control to do the selection in the first place.

For all practical purposes, the two are the same. You also fail to
consider cases when the behavior is a non-conflicting superset of the
operating systems conventions.

Native dialogs are not the same as having multiple <form> elements.
There are many situations where you might have more than one form on a
page, and not all of those forms have a submit button. Furthermore,
there are situations where you don't necessarily want there to be a
default button triggered by hitting enter.
So far as I can tell, this use of the "enter" key is not even
covered in the spec. It's just a common behavior added by UA vendors.
So, in this case, some clarification of how the "enter" key should be
handled with regards to forms may be appropriate.

This is invalid markup. In HTML, a <label> can be associated with
only one control, either by explicitly using the |for| attribute, or
implicit association by making a single <input> element a child of the
<label>. Having multiple controls as children of a single <label> is

Of course it's inappropriate, since <fieldset> uses <legend> for its
caption, not <label>.

I'll ask Microsoft to do that right after I get them to decouple
Internet Explorer from the operating system and file system.
Note that Mozilla and Opera already have the label passing behavior.
IE has it for explicitly associated controls.

What accidents? Provide an actual case where some real person was
significantly inconvenienced by label focus passing. And yes, the
threshold is SIGNIFICANTLY inconvenienced, since you are the one
proposing the removal of behavior from the specification. I propose only
a clarification of the HTML spec related to how labels handle mouse clicks.
