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

15 years ago, in certain circles it was well-understood how to load
one's own (possibly patched) software from the Ethernet side on the
old LanCity (pre-DOCSIS) cablemodems.

You can imagine what kind of hilarity ensued.
