Right. A dyslexic typo sorry doesn’t
That was my point. He needed a tool and didn’t have one so he wrote a
singular tool to solve the problem. We now consider that tool pretty much
standard equipment

Noel. Pls check the TUHS archives and I think
you will see sed does yet
exist in 6th edition when Joy wrote head in 1977. Certainly not yet at
UCB.
V6 doesn't have sed.

But note
that when wnj wrote head(1), Joy followed the
famous `Unix Philosophy' of doing one (small) job
well. Which means he did not add a feature *i.e.*
abusing, an old program, like cat(1), and add some new
switch to it that that told the program stop outputting
after n lines. Instead Joy wrote a simple new tool.
He didn't need to abuse any existing program by adding new
flags or the like; unless I am mistaken, `sed Nq', for some
number `N', does exactly what `head -N' would do on a single
file, obviating the very need for head(1).
