I've been using i3wm for years and have recently started doing deeper dives into the sorts of things that you can do with what's either already installed or easy to add (e.g. rofi for input, conky for display) [edit to complete the thought:] I really love how flexible and relatively straightforward it is to script up simple applications that have a fairly significant impact on my "quality of life"!
I switched from i3 to bspwm a few years ago and I have basically a "complete" setup.
I do occasionally make scripts like you mention, they're super fun, handy, and almost impossible to share unless someone else has the same niche knowledge and requirements.
