Why bother? It is one checkbox in the settings and then every keyboard has caps as control.
If you customize lots of things and carry your keyboard to many different computers, I guess doing it in hardware is marginally "better" than just using software, but ctrlcaps is common enough that the software is just there by default.
That’s the beauty of custom keycaps and boards with customizable firmware! Almost every premium GMK, ePBT, etc. keycap set will come with a Caps Lock replacement key labeled Control. It’s lovely.
So I just googled to see if my keyboard (Realforce 88u) has customisable firmware and apparently it has internal dip switches to configure the behaviour of ctrl and Windows keys!
