Somewhat related but I was disappointed to learn that Time Machine would no longer support Time Capsule post Tahoe, which I suppose is fair 8 years post discontinuation, but also unfortunate considering AFAICT the only real potential issue would be HDD degradation over the years? At the least, there have been plenty of system alerts noting this fact, but still annoying to have to buy something else. I know both AirPort and Time Capsule were an infinitesimally small part of their business...but they absolutely rocked when they were launched.
