Caution: This is a (semi-informed) SWAG.
In general, disk brakes require more braking effort than drums--smaller friction surface area--so the servo was added when disk brakes became predominant. I suspect this may not have been evident on the first disk-braked cars--didn't some cars come with disks and no servo?-- but was added when it became evident the booster would help.
Also, 'power everything' was popular in the 60s, so it could have been a marketing thing, too.

I have never understood why the later cars had--and presumably
needed--brake boosters whereas the earlier ones did not. Can anyone
enlighten me?
