Could be an issue in some cases, but mine only heats while water is flowing through. Otherwise it cools down. Also the input water in my region is clean and drinkable, so it hasn’t enough food for germs.
Legionella won’t make you sick if you drink it, only if you breathe it in. It exists in clean drinkable water all over the world. It’s capable of hibernation and able to survive without nutrients for long periods. So it’s at least a potential risk any time you breathe aerosolized particles from water that is not hot enough to kill it. Any type of water heater that heats to 60 degrees Celsius will kill it.
This may have consequences not killing things that like thriving in warm water.

Inline heating is pretty safe to do that, aye. I’d worry about listeria in a tepid storage tank.
