I more or less agree with you Frantisek.   There are throughput numbers
that are need for current gen and next gen services, but those are often
met with 50-100Mbps plans today that are enough to handle multiple 4K
streams plus browsing and so forth, yet no one talks about latency and
packet loss and other useful metrics at all and consumers are not able to
and never will be able to understand more that a couple of numbers.  This
is an industry problem and unless we have some sort of working group that
is pushing this like the 'got milk?' advertisements I'm not sure how we
will ever get there.  The big vendors that have pushed docsis to extremes
have no interest in these other details, they win on the big 'speed' number
and will advertising all sorts of performance around that number.

We need a marketing/lobby group.  Not wispa or other individual industry
groups, but one specifically for *ISPs that will contribute as well as
implement policies and put that out on social media etc etc.  i don't know
how we get there without a big player (ie Netflix, hulu..) contributing.
