The main point of using a very-high-level language (like bash) is that

As soon as you make it flexlbie, with command line options, you begin
typing getopt or GetOptions stuff and that's pretty much boilerplate.

Well, I do do that. Mainly it’s just a loop, though, e.g.

           break
       fi
       opt="${1:2:${#1}}"
       shift
       val="${opt#*=}"
       if [ "$val" = "$opt" ]; then
           val=""
       fi
       opt="${opt%%=*}"
       if [ "$opt" = "animation" ]; then
           animation=1
       elif [ "$opt" = "blender" ]; then
           blender="$val"
       elif [ "$opt" = "camera" ]; then
           camera="$val"
       elif [ "$opt" = "collections" ]; then
           collections="$val"
       elif [ "$opt" = "crash-protect" ]; then
           crash_protect=1
       elif [ "$opt" = "crash-retry-count" ]; then
           crash_retry_count="$val"
       elif [ "$opt" = "digits" ]; then
           digits="$val"

I would say, only a few lines in there count as “boilerplate” ...
