Still, I may be a little anal about this but I align with this. I quote everything in bash. In this case I would do single quotes as it's a literal. You never know when someone with lesser bash knowledge will modify your script and put a variable in there. Shell expansions are nothing but footguns everywhere. Proper quoting hygiene and `--` goes a long way

I found it reasonable because there's no need in this specific case but you do often use quotes and this could be a good middle ground of annoyance (line complexity) and getting the character distribution somewhat right
