It looks like it's ~4 years since we updated some of these, so do a bulk
update.

Verified that the before and after generated configs are exactly the
same.

Yep, that's guaranteed by the tool (modulo bugs).

Which begs the question why update them? The answer is that it can be
confusing when the stored defconfig drifts too far from the generated
result.

And it becomes hard to update them, e.g. for enabling or disabling a single
option.

Now the big question is: do they still work?
Plainly ignoring any bugs introduced in the code, there are probably several
"select" statements that have been removed. 4 years ago, they automatically
selected some critical options, while now, they're no longer selected, causing
breakage.

Yeah true. So far no one has yelled at me, so perhaps we got lucky :)

cheers
