I think you're conflating two separate things here.

The major difference between user mode programs and kernel mode programs is security and stability (at least in this context). Things in kernel mode have basically no restrictions on what they can do, from a security sense. Things in kernel mode can also crash the thing they're part of: the kernel. That's a blue screen (or cyan, now). One of the reasons those blue screens are so much less common is that Microsoft really pushes OEMs to make userspace drivers. If they die, they just get restarted, no need to crash the whole OS.

The other issue is of installing user-facing utilities alongside the driver. That needs to stop. It's orthogonal to the kernel vs user mode issue though, because Razer can make their UI run in kernel mode. It's a horrible, terrible idea that no one will enjoy, but they can. And really, we want the drivers to run in user space too if we can.
