Agreed, but walking even a moderately large tree over the network can really hammer home the point that this offers a significant performance enhancement as the latency of access increases. I've found that kind of comparison can be eye-opening for folks that are used to only operating on local disks (even spinning disks, let alone SSDs) and/or relatively small trees (distro build trees aren't that big, but they're big enough for this kind of difference in access overhead to start getting annoying).
Oops, forgot to add - I agree this isn't a blocking issue for the PEP, it's definitely only in "nice to have" territory.
Cheers, Nick.
