The only part I find questionable is the use of tools written in shell. Shell is a very difficult language to understand and use correctly. To the credit of the author, he is aware of this and the code is linted using shellcheck. Still, I wonder if it wouldn't have been a better idea to write the utilities using Python or Lua or even (gasp) C! (Or Rust, or Go or ... Just pick one that isn't completely esoteric and isn't Perl, then stick to it.)
