If you want to run some programs and change flow based on what they do why wouldn't you use language that is all about running programs? That is what bash is good at less so other other bits of programming. As a contrast I have been experimenting with using Lua and lua-posix to write a wrapper around ffmpeg. Just some batch encoding tasks nothing too complicated. The logic is easy, spawning the main encodes isn't difficult, reading the json output of ffprobe is hard.
