So you needed it for use by a human rather than for use by ELisp code?

It's a hack, indeed, and it could fail if the hook function was careful to
let-bind `inhibit-read-only`.

Personally I think I would have used `C-x h M-x write-region RET` (or
fixed my config since clearly having this hook function active for this
file is wrong).
