So this fix requires people to have a different dictionary file from 8.2
to 8.3, and to manually edit the file? That makes upgrade even harder
and more error prone.
Seems easier to do it the way Tom suggested and only emit notices in the
first case.
I notice there's still a placeholder in the docs for how to upgrade.
Perhaps if we wrote that now it would make it clearer where the
difficulties lie?
