Does that actually affect real science, or is it just a matter of astophotographers wanting a nice picture without streaks? It's not like long exposures have to be done on film these days. Anomalous light sources can be removed in software. I think if this is affecting basic science it's a real concern, but if it's just a matter of making long exposures of galaxies and nebulas less pretty then I have a hard time being overly concerned about it.
