What do you guys think of 980 being removed and replaced with BART's Red Line?

I mean, given that BART wants to de-interline one of its lines and reroute it through a 2nd transbay tube (likely interlining with a rerouted Blue Line).

If this happens, 980 will be renumbered 24 again. A NB 880 to EB 580 ramp could be provided as a workaround at the MacArthur Maze.
