But on closer look, I saw caps lock was changed to ctrl. Which is what I do on all my computers
I hope the Framework ecosystem grows so we might someday see a keyboard like this for it

But then how do you yell at people on the internet?!?!
Let's use `xev`'s `state` field for reference:
First, `state & 0x10` is NumLock which is the only modifier that's often set. Software knows to mask out this and a couple other modifiers when dispatching keyboard shortcuts.
Second, `state & 0x02` is CapsLock. Software that detects CapsLock as a modifier will work correctly with double-shift-as-capslock.
Unfortunately, `state & 0x01` is Shift. Software that reads CapsLock as a keysym (often e.g. games that use it as a "turbo" toggle) will often fail, because when double-shift is pressed, the shift modifier has been set. And it's generally considered a bug to ignore modifiers when dispatching keyboard events.
Unfortunately, there is no event for just "`state` changed", it is only dispatched alongside some other mouse/keyboard event. If you press just `shift` you'll see that it doesn't update yet for the just-pressed key (and fundamentally cannot due to how it has to work to switch between keycode->keysym mappings).
