This is the best way. It's also the way the Shellcheck ~~wants~~ sometimes recommends.

@bloopernova As you mention it, here the links for anyone interested: Online tool https://www.shellcheck.net/ and you can install it locally too https://github.com/koalaman/shellcheck .

While this looks like a handy tool, it does make me think shell scripting itself needs a cleaner approach than what we have currently.

This isn't true. Shellcheck doesn't insist on braces unless it thinks you need them.

Oh! I didn't know that (um, obviously lol)

I'll edit my comment.
