This is exactly how I do things. I've got a whole folder of "special
scripts" that require su.
But getting the script developed usually requires some experimenting as
root to get the right order down and verify that it works. I see that
as a whole lot safer than just writing the script from scratch and
sudo'ing it and hoping it works. Just me though.
To further bastardize the analogy, sometimes rock-climbing with scissors
is necessary, but if you don't hang a pulley system when you get to the
top and use that from then on to lift the scissors up and down the
rock-wall, well, you're just asking for it.
