Sure I cannot use /proc/sys/kernel/hotplug any more, but that's just another inconvinience. As long as hotpluging works for you, why should you worry? But what when it's broken?
For example Tandberg RDX drives: with the 4.x kernel, udev does not show any events when inserting a cardrige. About year ago (3.x kernel and older udev) I got "ACTION=add" when inserting a cardridge. Now i only get these events when I insert the cardridge and then call "partprobe" as root. Great improvement. So probably there is something is a bit odd. Same goes for CD/DVD. Was it udev? Was it the new kernel? Did sombody mess up the transition from HAL? Let me stress: I do not have these problems on BSD, nor when I start my timemachine and go to wheezy.
