Actually, here's the patch that I'd suggest.
It reverts the code to its Jan 2021 state, which, in my book, makes it
safe enough.
The current sort predicate is quite severely broken, so "no sort" can't
be worse (especially since the list is supposed to be sorted already).
Also it re-instates the "prefer a builtin package" which was lost along
the way.
