Can't happen soon enough. Personally, I'd wish this would go much further and would allow every device to be flashable, with only a few exceptions for safety, like cars.
There's also a certain irony that certain other places will go to bat for right to repair, and then turn around and say "Actually, I want to live in a walled garden.", not realizing that these are two sides of the same coin.
Beyond pure principle, flashing would be very useful when it comes to extending the lifecycle of the device beyond its original purpose. They're quite powerful and could be turned into a small server for example, similar to a Raspberry Pi. While lacking in ports, they do come with a battery, wifi+cellular and multiple cameras already built in.
