Right, but once you start hiding NET_VENDOR_DRIVER_XYZ under a

old defconfig breaks.
To be clear do we actually care about *old* configs or *def* configs?
I think we care about oldconfig but maybe less so about defconfigs which
are in tree and can be updated.
The oldconfigs would have to not be updated on any intervening kernel
in the last 10+ years to break, right? Or is there another way that an
oldconfig would not have the vendor config set to y at this point?
That sounds very unrealistic, so yes, I don't think at this point that
would happen. Even if you had your 15 year old .config file and ran make
oldconfig today, you would have some work to do to make sure it still
runs on your hardware.
