That has been my experience as well (only from the RF side) and I would
believe this was a design choice.   The ISP usually wants to keep control
over the firmware versions of the CM for various technical/support reasons
versus having consumers mess with the firmware.

My employer managed a handful of small DOCSIS networks for a while where 99%
of the modems were Motorola, and as far as I know, there is no way to push a
firmware update to the modem from the ethernet side...only from the RF side.
