Maybe it's because I've spent part of the last week poking
around with synchronous serial protocols (I2C, anyone?) but
I think I may have a useful analogy here.
You can divide serial communication protocols into two
classes, those which included embedded clocking and those
which rely on external clocking. One technique isn't
naturally superior to the other, and in fact there are
times you want to use one or the other, depending upon
design goals, circumstances, etc.
We can think of the DNS service as commonly used today as
having "embedded clocking", in that the knowledge of where
to go to resolve a query is assumed as part of the query.
This is less flexible than having this knowledge outside
the query but it's simpler and does lead to a simpler
system. It also ties everyone together in ways that,
because of admittedly non-technical decisions made outside
the scope of this list, the resulting service is running
up against constraints a lot earlier than might be
expected absent such decisions. Sadly, now that
"steampowered.com" is gone I can wail all I want, but I'm
not getting it as long as we all use the same resolvers
(ie. the same "embedded clock"). This is the only way to
guarantee universality of response.
A clock, whether embedded or external, is only useful if it
is used by both the sender and all the recepients. Given the
goal of having a single clock, there are indeed many
different ways to achieve the same result.
You cannot, however, have two of the devices on an I2C bus
decide that the clock the rest of the bus is using is
defective, and just decide to use a better clock on their
own.
Additionally, I think it is also important to recognize that
domain names are now an integral part of trademarks and have
meaning far beyond translating a name to an IP address.
Suppose the IETF were to somehow get the crazy idea to
radically change the entire domain registration system, and
as a result Disney no longer owned "disney.com"?
Does anyone really think the courts would back the IETF?
