If I only had one router, it could not stay mounted in a router table all year. Yes, you can make dovetailed drawers with a router mounted on a table, but I much prefer to use my Leigh jig. I usually wait until after assembly to round over edges, and cabinet boxes are just too big to wrestle onto a router table.
Over the years, I've kept adding to my tool collection until my router count now stands at six. The big Triton lives in the router table most of the time, except when it is ousted by the big Porter Cable which has one half of a rail/stile combo correctly adjusted and ready to go when I drop it in the table. A Porter Cable plunge router holds the other half of the rail/stile combo. So I change routers instead of changing bits and fussing with the height adjustment. I have two D-handle fixed base routers that stay set up for dovetailing. And the little Bosch Colt keeps a round-over bit in it's mouth already set for quick duty.
Not saying it can't be done if you're building small stuff, but my routers go in and out of the table quite regularly.
“We should be careful to get out of an experience only the wisdom that is in it and stop there lest we be like the cat that sits down on a hot stove lid. She will never sit down on a hot stove lid again and that is well but also she will never sit down on a cold one anymore.” - Mark Twain
