I’m nowehere near the level you are, but I like to reduce clutter (and overhead) and I just started doing that again a couple of days ago in light of Backblaze consuming lots of energy.
So far I have removed Backblaze (moved it to a networked Mini), uninstalled Dropzone (was using energy), and a couple of maths and GIF apps I never really use. I also stopped iMazing, Downie, Gifox and Air Server from automatically starting.
I also have HomeControl that I haven’t gotten into as my Home is still being set up, and that appears to be using unnecessary energy. I’m going to give it more time to prove itself, though.
