A mature tree can throw on the order of 5,000 winged seeds in a year, and those samaras plus the seedlings they produce are the actual maintenance burden rather than any leaf litter. Given its size, autumn leaf drop is minor and rarely the reason anyone picks up the phone.
Small — roughly 15–20 ft tall and frequently wider than it is tall — with a typical landscape life around 20–30 years, though well-sited specimens run longer. That makes it a low-cost removal: a ground crew and a chipper, no crane, no rigging, and stump grinding is trivial.
