Well, as has been mentioned numerous times here and in many other threads: I think for most people (me included) it's really not as much about a new feature to edit the device list as it is about fixing a major outstanding bug that adds bogus "unnamed device"s to that device list. To make matters worse, it's specifically these bogus "unnamed device"s that persist in the list, and don't disappear after 30 days.
I understand from a range of threads here and on Reddit that the internal model for Google teams and employees is to be rewarded for new features to progress their internal Google career; and little to no credit is given for fixing major bugs in existing products and features. I was sceptical when I read about that at first (as it seems extremely silly and literally promotes adding messy broken features, for the next guy to fix; who won't fix it of course), however, the customer experience here effectively backs this up. Again, to be clear, we're talking here about major outstanding bugs that have persisted for several years, without a single hint at these being attempted to be resolved; and this for a paid product.
All that said, a simple feature to remove a device from that list; how hard can it be? Just assign the ticket to someone already and buy them all their coffees for an afternoon.
