lgarron: I originally wrote this as an experiment but it might be worth landing.
This change reduces the (binary) list size by ~5% (which is less than a release
worth of additions) on all platforms [1]. It could help keep the size manageable
for a while longer until there is a better solution.

What do you think?

I'm sorry, this got filed away a long time back. :-(

5% is not much, but then it's pretty significant compared to any pruning we
could do.
Is this still usable/ready for review?
