My drain pan is plastic, it is 10 years old, and it still works fine. In The Villages, most water heaters are located in the garage near the garage door, so a leak probably would not cause major damage to the house. Also, if you hired a plumber to perform these maintenance tasks annually, you would spend way more money in 10 years than the water heater actually costs to replace.

I concur with some of your thoughts but a professional company would ensure that the prescribed PMs would be able to be performed. In some cases a warranty may not be honored if the recommened PM schedule was not adhered to.
Maybe a uncontrolled leak near an interior wall doesn't concern you but it does me.
As far as the rest is concerned, best let the professionals explain it.
