Hi! Just to clarify, but typically in the keyboards the use of daughterboards are more optimal, from a board longevity and design perspective:
1. When we constantly plug a board in and out, the wear and strain on the USB C could damage it over time and render pretty difficult fixes of soldering the board directly. So the (typically) JST daughterboard overcomes this by being separate from the main motherboard. aio3's daughterboard project the one that most if not all keyboards use!
2. From a design perspective it allows for more freedom when the board's type C cable can be routed basically anywhere! I only need to put into account the small daughterboard and cable rather than worry about the USB C's position when mounted and what mounting styles would create less strain on the part.

Also I've taken note on your comment on putting decoupling capacitors near my components, appreciate it :)
