How about "no fault"?

If there's any "fault," it is the difference between a computer
mindset and a CE product mindset.

When ATSC A/53 was being written, the WWW didn't exist yet. We
would "browse" the Internet with tools like Gopher.

The CE minset would be to continue to support Gopher. The computer
mindset is to assume that everyone by now will be using not just a
browser, but IE Version 6 (or equivalent), and Gopher and Archie
are distant memories.

No scheme is immune to this. You wouldn't fault DOS and TCP/IP for
not supporting HTML, would you? Just hadn't happened yet, and it
rendered a lot of hardware and software obsolete when it did

The IP/PC way of implementing dual audio decoders is simply to
start writing applications that require multiple decoders, and
then let the consumer decide when to upgrade his equipment to
benefit from the new features. In a couple of years, you assume
all consumers have bought the necessary new equipment.
