The fact is that the input of sed is "$1" itself. An redirecting the output

No, reading and writing to the same file usually doesn't work (unless
you have a very good reason to do it). But using printf seems weird. It
just forces the shell to hold the whole output of sed in memory to be
able to pass it to printf.

Isn't a more conventional way to do that

sed -e '...' "$1" >"$1".new
mv "$1".new "$1"

?

Is sed -i not portable or what is the reason not to use it?
