A sacrificial anode protects any exposed steel inside the tank from corroding. Doesn't matter the type of heat source.
Guess I should look into replacing ours in a few years. Would that have prevented the rust-out that killed our tank after 10 years?

Take the anode out of the one with the rust hole in it and see what's left.
Your local plumber should be familiar with the water supply in your area and if it is extremely hard would recommend checking the rod for calcification ( one of the maintenance issues with tankless ) or if it is extremely soft the rapid deterioration of the rod.
If the tank rotted from the outside in on the bottom from proximity to the damp basement concrete floor like so many do here ....
