Thanks for the examples. We considered doing something along the lines
of your first suggestion, but it becomes awkward when every callback
defined in the sidebar needs to explicitly clean up the main
component, whereas the decoration ensures it'll happen automatically.
It never occurred to me to use announcements, but I don't think they
solve this issue.

When modified to use #home, though, I guess the decoration is actually
pretty reasonable.
