* larger packet sizes,

* simplicity, and

* all modern OS support IPv6 by default.

There is also:

<https://tools.ietf.org/html/bcp177>

"
   o  IPv6 support must be equivalent or better in quality and
      functionality when compared to IPv4 support in a new or updated IP
      implementation.

   o  New and updated IP networking implementations should support IPv4
      and IPv6 coexistence (dual-stack), but must not require IPv4 for
      proper and complete function.

   o  Implementers are encouraged to update existing hardware and
      software to enable IPv6 wherever technically feasible.
"

No reason not to comply on private channels created between Squid and
its helpers.
