Found this tweetstream, here folded together, when looking for something
else (now lost) in my twitter archive:
==========
Things I miss from the v8 shell.
1) All shell output was valid shell input.
2) Typing dir/cmd would find the command $PATH/dir/cmd. Subdirectories of
your bin, in other words.
3) Functions were exportable. For one brief shining POSIX meeting, that was
true in POSIX too but then...
4) The implementation was lovely and easy to understand. (No, it wasn't
shalgol. Bourne fixed that for us.)
5) That I could learn things from it, like how to write a recursive descent
parser.*
6) It ran in cooked mode.
As expected, all that work making it a great shell is lost to history.
https://t.co/IzApAUSmzN is silent. Well, the code is released now.

Sorry if this is obvious to everyone else: What does this phrase mean?

I've never been convinced by that particular argument, since if you
want command-line completion, the terminal driver is way too
low-level.
I suppose you could have callouts from the kernel to applications that
were willing to provide context-sensitive command-line completion
lists, which is how Multics handled things (trivia for the day: the
libss library used by Linux's e2fsprogs and MIT Kerberos v5's kadmin
interface uses an API inspired by Multics' subsystem library), but the
point is that you can't do it all in the terminal driver.
Cheers,
