To improve readability suggest two names, maybe unalias_gfn() and
unalias_gfn_instantiation(). boolean parameters are hard to read at the

Also we've discussed in the past converting aliases to private slots
(and also echo aliases >> feature-removal-schedule.txt); maybe that is
an easier way of verifying everything still works.
