The reason that we were able to get from 110b aud to V.92 without
active cooperation from $TELCO was because $TELCO didn't have to do
anything to make it happen. The extant copper pair was (mostly) good
enough for technology to advance "at the ends" for quite a while.
Similarly, since this was all done over the voice network, $TELCO
didn't have to actively cooperate in moving the data along, beyond
what they'd do for any other phone call.

DSL[1] and DOCSIS require active cooperation from the carrier.  Ergo,
tech advancement in the carrier-assisted data transport arena is
dependent on the carrier cooperating.

[1] except for "alarm circuits" that somehow got repurposed for
point-to-point DSL circuits (or T1s, for that matter), in which case
you're back to tech advancement happening in the CPE, not the medium.
