I understand where you're coming from, however, these patches make it a
lot easier to work with large chucks of binary data. I think it makes
more sense to have these patches upstream, even though committed code
may not necessarily have all the features enabled, as it means that
devs won't have to apply out-of-tree patches during development to make
larger dumps manageable.

Where's the mixture? What would you propose instead?
