@spalger Hey, do you think I should be backporting this to 7.x? Or do you know who might have guidance on that? Thanks.

[spalger]

I think it will make backports down the road easier if the limits for the bundle are the same in master/7.x, otherwise we'll have conflicts any time the master bundle limit is changed.
