My personal opinion is that no one should be using `which` in maintainer
scripts and that no one should be using `which` in an interactive shell
unless it is a builtin of that shell.
There are a ton of postinst scripts relying on `which` right
now, which makes sense because `type` and `command -v` used to be
optional extensions to POSIX and not guaranteed to be provided
by /bin/sh.
