Then you didn't look in the right place:

However, there are missing I-Ds from 1994 or earlier, from the days when
ftp was the only method and expired drafts were taken off line immediately.
The Wayback machine also only goes back so far.

Some IDs were written before the IETF asserted its right to archive and
provide access to them indefinitely through copyright transfer.
The original authors had the right to prohibit distribution of that
material, and some (myself included) have asserted that right
vigorously. I.e., it's not merely a matter of what was "lost" but also
"who has the right".
