This was the case already in HTML 4.01, though it was implemented slowly
and was not much known among authors.

Generally, attempts at defining "quirks mode" would mean making it an
alternate mode and will not be successful due to the wide variation
across browsers and versions. It's called "quirks" for a reason.
Specifically, as some browsers already support rowspan="0" in quirks
mode, and some don't, you cannot ensure backwards compatibility no
matter how you define it. For the bulk of legacy pages, it does not
really matter, as they do not use such attributes. So the question is
really what happens to newer pages where people may have used them after
observing that some browsers support them. The current situation is
inconsistent across browsers, but it does not help to change it; it
could break existing pages written to work on browsers that support
rowspan="0" in quirks mode.
Similar considerations apply to colspan="2".
