Isn't it? I have always treated it as the most-portable option for this
(compared to, say, `which`).  It is in POSIX as a utility (albeit marked
with XSI), which even says (in APPLICATION USAGE):

  Since type must be aware of the contents of the current shell
  execution environment (such as the lists of commands, functions, and
  built-ins processed by hash), it is always provided as a shell regular
  built-in.

All that said, I think Todd's patch makes perfect sense even without
wanting to avoid "type".
