That’s awesome, reminds me of the bus drivers wearing skirts!

For some cases that doesn’t really help. For example if you do a large survey of the sky for transient peak detection you don’t have the time to spend multiple lights on a single part of the sky. I’m not sure if the satellite trail removal is helpful for that, but the trails themselves are certainly an issue for sky surveys.
