If the ISP does so, they are stupid.

As an ISP, if my users have IPv6, they can go directly to many of the
traffic-intensive sites (youtube, google, ...) - which directly translates
to (significantly) "less load, less sessions" on the CG-NAT boxes.

Less load on the CG-NAT boxes translates to "less $$ to be paid to the
vendors for larger boxes, and for sufficient public IPv4 addresses for
the NAT pool".

T-Mobile USA realized this like 10+ years ago and went IPv6-only(!) for
their mobile customers - with a NAT64 translation layer, for those sites
that still only provide IPv4.  To some extent this was driven by "yes,
IPv6 is the way to go", but to a very large portion by "we do not have
IPv4 addresses, and we do not want to go out and buy legacy stuff for
lots of money if we can future-proof our network right away AND save
money at that".


Did I say that ISPs charging extra for IPv6 are just stupid?
