My point is that the option should be there, at the consumer level.
If not for fully symmetrical service (I admit that 50MB/s upstream is a
tough pipe to fill), at least for significantly higher upstream service
than is currently available in most neighborhoods.
There are so many use cases for this, everything from personal game
servers to on-line backups, that the lack of such offerings is an
indication of an unhealthy market.

Daniel,
We'd have to come to some standard definition of, "But even if 1% of
users would reasonably be using a fully symmetric link to its
potential..."
As I said, I have visibility into a large number of symmetric
connections and without exception they'd fit well into a plan that
offered upstreams with that had a fractional speed of the downstream.
Now, keep in mind I'm not talking about 1/10 as a ratio here, but 1/5
would accommodate ~99.2% and 1/4 would fit ~99.9%. It's also
important to note that all of these accounts are in the >25mbps down
territory so their upstreams are >5mbps.
What I see when I look at customer satisfaction ratings is a very
strong correlation with low uplink speeds and a high satisfaction rate
when we look at uplink speeds greater than 4mbps. What I don't see is
an increase in customer satisfaction as upload speeds go past ~6mbps.
Conversely, increases in customer satisfaction with correlate with
increases in download speeds past ~30mbps before the correlation
starts weakening.

The statistics certainly *should* be used when provisioning
aggregate resources.
But even if 1% of users would reasonably be using a fully
symmetric link to its potential, that's a good reason to at least
have such circuits available in the standard consumer mix, which
they aren't today.

Daniel,
Well, I wouldn't call using the mean a "myth", after all
understanding most customer behavior is what we all have to
build our business cases around. If we throw out what
customers use today and simply take a build it and they will
come approach then I suspect there would fewer of us in this
business.
Even when we look at anomalous users we don't see symmetrical
usage, ie top 10% of uploaders. We also see less contended
seconds on their upstream than we do on the downstream. These
observations are based on ~500k residential and business
subscribers across North America using FTTH (mostly GPON),
DOCSIS cable modems, and various flavors of DSL.

It isn't that most, or even many, people would take
advantage of
equal upstream bandwidth, but that the few who would need
to take
extra measures unrelated to the generation of that content
to be
able to do so.
Given symmetrical provisioning, no extra measures need to
be taken
