If I don't fix bugs and I don't help my customers with setting up servers and the like I don't think I'll get new projects with them. Why would they trust a developer that disappears? It's as simple as that.

Some of those activities are paid, but fixes close to a delivery are not and it's OK. Usually I set up a maintenance contract for quick activities, like small new features or investigating puzzling events (not necessarily bugs.) I have a ticketing system to keep track of those activities. Customers have access to it.

Obviously one has to make clear that maintenance will slow down development.
