I agree with that.

No, I think it should be allowed. There are some cases where, e.g. some
previous option you picked forces certain other checkboxes either on or
off. They're disabled because you can't change them, but, some of them
might need to be on.

It is.
   "User agents implementing this specification must select the first
    (non-disabled) option element of a single-select select element
    with no otherwise-selected items."

Hixie would have said something about it being nonconforming to have no
selected options at that point, and wouldn't have had multiple examples
of <select>s with no selected options, if that was what he meant.
