It appears that Michael Thomas <mike () mtcc com> said:
anything that ISP can do if they don't supply the ÇPE? What percentage 
of providers do supply the CPE in the form of cable and dsl modems, etc, 
that they could solve the problem with a swap out?

In the US at least, although cable customers can use their own DOCSIS modem and
a router, most don't.  All the Comcast customers I know have a combo box that
is a modem, router, hotspot, and telephone adapter.  It has full native IPv6
support, of course.  I poked at one and found that some functions like port
forwarding are only managed remotely by logging into the Xfinity website.

DSL and fiber modems aren't standard like DOCSIS so you have to use the telco's.

Anecdotally, when I've rented apartments in the UK and France they all had
provider CPE too.
