Makes sense. I even wondered myself why there is no way to override
an --ipv4/--ipv6 in command-line back to "any" with an option added
after it:

    $ cat my-fetch
    #!/bin/sh
    git fetch --ipv4 "$@"

    $ ./my-fetch --ipv46

But how about making the command-line and config option a list?
(renaming it to ipversion, as elsewhere in the discussion)

    git fetch --ipversions=ipv6,ipv8

Given multiple times, the last option wins, as usual:

    $ cat my-fetch
    #!/bin/sh
    git fetch --ipversions=ipv4 "$@"

    $ ./my-fetch --ipversions=all

BTW, transport.c already converts transport->family to bit-flags in
connect_setup.
