As a fellow Colemak user who has used other layouts in the past, I have to wonder how many of the issues I have with my keyboard now are because of Colemak, since I didn’t seem to have them with Dvorak or Workman.
But maybe I’m just salty that my WPM never recovered fully after switching.
Any PCB that’s compatible with QMK firmware (and maybe others, but QMK is easy & the most well-known) should be able to be flashed with any layout, so even if you get tired of Colemak, you can change it to whatever you want. :)
Edit: You can also get hot-swap sockets that allow you to change your switches without desoldering anything.
