No, it doesn't. You throw away the ordering the kernel naturally has.
If you write out events from within the kernel, you know that you'll
never see a replug before an unplug.

Writing a pipe from the kernel, which is generally called a character
device, has other advantages as well.
You can report events dropped as errors. The hotplug spawning
scheme cannot do that. No spawning cannot differentiate between
no event and an event lost.
