there's a valid reason why the download range couldn't be variable and
negotiated and that's it's completely impossible for one to have 20Mb up
and 1.5 Mb down.

VDSL2 ITU G.993.2 supports variable and symmetric negotiation of rates. obviously distance is a factor, cause you're down to ~50Mb/s at 1000 meters.

at&t and bell south, now at&t and at&t had vdsl rollouts that could in
theory be upgraded to vdsl2.

If you were in helsinki, I know Päijät-Hämeen Puhelin ( would
sell you 100/24 vdsl2 for around 80euro a month.

As cable was mentioned in earlier posts.. There are also (proprietary) solutions leveraging cable for symmetric 10/10 or 100/100 Mbit/s.

One example I'm aware of is Teleste's ETTH technology:
