The cause of mouse stuttering when pressing keys has been 100% found

I sort of agree on the continuance of support for Windows 10, but it's diminishing returns for development time. I don't think most developers follow the specific end of service/end of life cycle of older operating systems. It's just a cost/benefit equation at the end of day for large studios like this. Indie devs would likely work diligently on it, but not these guys (I imagine). I'd be curious to know what percentage of the players are on Windows 10. There are definitely people left out because of older hardware. For instance, needing TPM and secure boot for the anti-cheat to work. So that will likely weed out a lot of people still using older operating systems.
