As I said, I'm sure it will be fine. I wouldn't hesitate to use it if I had it on the shelf, I just might not buy one for that purpose if I was looking for a new one. Yes, you would be looking for burned/sticking/welded contacts, and it is very doubtful that a device that is that robust would have any problem other than the lights staying on if the contacts welded. The inrush on capacitive loads is extremely high, so the problem would take take place when the contacts first closed or bounced on activation.
I guarantee that there are people who are successfully using a timer that has a fraction of that one's capability. It might simply be a case of GE not wanting to pay for the testing because they didn't anticipate much action out of the lighting market for a water heater timer.
