It's also not about seniority or competence. Writing kernel mode drivers is being given the task of juggling running chainsaws with real chains while on a balancing board. "Success" is declared when you're able to do this in a lab without there being an issue, ignoring the fact that in the real world there are dodgeballs being thrown at you. Also, no one I've ever worked with writing them has ever wanted to maintain & improve the quality of the drivers they wrote - they wanted to move on to "interesting" work as quickly as possible. This includes myself. The work isn't interesting, fun & usually not important to the business.

In this case, why does a mouse driver need to live in the kernel in the first place? Microsoft should be improving the HID layer to make that unnecessary.
