    a meaningful intergalactic exchange isn't really possible anyways.

To be fair, if you would have a civilisation capable of using a supermassive black hole for communication performed by steering huge chunks of matter through a carefully calculated trajectory, all while correcting for accretion disk dynamics and all that ergosphere weirdness, you would probably be close to the (stable enough) Einstein-Rosen bridge technology. Then you would have no excuse to not travel :D.
