I can't remember enough of how the syntax tables of sh-mode are setup.
So I suggest you just try it and see how it fares.

W.r.t only tweaking the SMIE behavior vs affecting `kill-sexp`, I think we
have `kill-word` for smaller chunks, so I don't see a convincing need to
use `kill-sexp` to stop at `/` boundaries.

But please add regression tests when you do that (and when you find
that it introduces new problems, please add those cases as additional
tests).
