IIUC there are keyboard shortcuts to go up/next/prev, whereas there
aren't keyboard shortcuts to go to one of the breadcrumbs (other than
the last one which is just "up").

This said, I agree that not being able to click on them with the
keyboard is not the end of the world.
IOW, using an after-string would probably be an OK compromise for 23.2
(better than dropping breadcrumbs altogether).
