Proton is just pre-built Wine with Valve patches. Wine existed for years and DXVK wasn't Valves' own project. They just sponsored some open source project and driver improvements and integrated it into Steam. I seriously doubt that if you count every single developer that Valve hired to work on it as well as sponsored 3rd-party developers there likely gonna be 25-30 people or less. I pretty sure that more people worked on Stadia within Google than all people working in Valve on all of their projects.
