The bad old days, when we walked 5 miles uphill to and from school, were not pretty: when cpp was an optional compiler pass and /usr/include didn't exist yet, only the kernel bothered to #include headers, and the number of bugs in V6 Unix programs because somebody had copied a struct declaration out of a manual page and then the real struct changed (or they had copied it incorrectly in the first place) was considerable.
