You never had to use it for escaping in C/Regex/Troff/etc?

ASCII keyboards had \ unshifted long before the PC.  The ASR-33 didn't
have it (it didn't have pipe at all - backslash was on shift-L), but
every DEC keyboard I can find did, as did the ADM-3a, and incidentally
the Symbolics Lisp Machine's keyboard.

I had suspected the reason that [\] ended up as the unshifted characters
is because {|} were not available on uppercase-only keyboards, but I
can't find any uppercase terminals that had separate keys for them (the
ASR-33 had them on shift- KLM). I expect that's also why ^, on shift-N,
was used for pipes rather than the vertical bar in the earliest versions
of Unix that had them.

What terminals did you use, back in those days?

(Incidentally, I can find *literally no* pictures of a Teletype 37,
and no sufficiently high-quality closeups of a 38 to determine its
keyboard layout)
