Nothing really. They would not be added today. It's from the time
everybody added their favorite stuff to sysfs, and nobody had a real
idea in which direction the stuff was supposed to go. :)

We only need "add"/"remove" and "move" for renames or re-parenting,
and "change" when stuff changes.

The "online"/"offline" are not useful at all, and ideally should just
use "change" for their state and pass the state with variables or
sysfs files.

No new subsystem should ever use these events.
