To be honest, I think traditional shells are now only good for environments where you know you aren’t doing anything too weird and all the most likely inputs work as expected without a lot of effort. This is spending time wisely; just because everything except a zero can technically be part of a Unix filename doesn’t mean that I want to invest hours or days making damn sure everything works for pathological cases. If I actually do want to guard against every case imaginable, I immediately switch to Python or some other language that at least knows how to quote things unambiguously without a lot of effort.
