@anmolnar I believe you misunderstood my comment above:
> likely this change will go into master (3.6.0+) - impact on backports.
I'm assuming we would want to take advantage of this library across the board.
(can we do that? I assume yes?)
> Sure, I'll have to backport it to branch-3.4, it will need some manual
work for sure, but I don't expect it to be the end of the world.
I meant that I was planning to only commit this change for 3.6.0+ - I am
generally reticent to add a new dependency so late in the 3.5 train. Do you
feel strongly otw?
