pkg(8) is actually smart enough to realise that the ABI-version of the
installed packages doesn't match either the ABI-version of the running
kernel[*] or the ABI-version of the repository and it /should/ attempt
to update or reinstall all installed packages to fix that.

Much of the time that will "just work" -- but not always, which is why
the standard advice is still to delete and reinstall all packages on a
major version upgrade.  Working out when and why pkg(8) can fail to do
this correctly and teaching it how to get it right would be a really
useful contribution.

[*] This can be overridden, so it is possible to run eg. a 10.3 jail on
an 11.0 host and maintain the packages with pkg(8).
