For vendors the model "3 months and move" on is not really an option,
but that is besides the point here.

It's not even that EoL is upon us.  It's that fetching updates for
a system that still has updates but ran into EoL before fetching
those updates will inevitably indicate a failure during fetch:

# freebsd-update fetch && freebsd-update install
# freebsd-update fetch install

This will not work, even though updates are fetched / pending.

In contrast, this works fine:

# freebsd-update fetch; freebsd-update install

I don't know how this is useful for scripting if we are supposed
to check errors, but in this case can't check for errors because
we require available updates to be installed.
