Yes, exactly.
I know we're all obsessed with computers and stuff, but those guys were damn good at what they did, and shouldn't be underestimated. (Whether the maps are at an appropriate scale is a different issue.)
But there's very little, if any, effort in keeping the quads up to date anymore. All the effort is focused on the national atlas.
