Yes. I would add to this list:
- it is conform to makefile syntax
Because it is so easy to mix make and shell files
I'm using ${foo} because the "context switch"
between both worlds is easier.
And sometimes I'm using constructs like
${foo:="foo"} or ${foo:-"foo"}.
Those constructs match better if I'm using ${foo} too.
