Not quite that bad. All Starlink sats are in a low enough orbit they will be down in 5-8 years. Not only does the low altitude improve latency, the passively induced immolation allows an easy way to free up room for more advanced satellites. Unlike geostationary sats, the old Starlinks will not require parking or monitoring. It's the GPS satellites and higher orbits that are a problem; even ISS and Hubble are losing height every day and require a boost. On the last service mission to Hubble the astronauts added a docking feature, so it's possible to send a robot vehicle to perform that boost before it is too late.
