Wow. Thanks for this. I've bounced off a number of tiling WMs on MacOS over the years - Amethyst, Yabai, others I can't remember - but Aerospace is really excellent. Can't believe I've never heard of it before. Love the custom implementation of spaces as a solution to what ails a number of other tiling WMs. I installed it this morning and disabled the mish-mash of Rectangle Pro, Better Touch Tool and OS kb shortcuts I'd been using.
