It depends on your goals. Relying on scripts running commands and parsing their output is not what I would call
sound software design. So much can go wrong. If you are just putting together some tools do to some light work it's fine, though.

It's worth noting that the ZFS command line tools are explicitly
designed to enable relible scripting if you use arguments like -H (no
headers) and -o (extract specific columns).  I talked about this a bit
at the end of this presentation:

I know, again it's not exactly the optimal way to do it. Call me old-fashioned :)
