i adjusted my heaters max temp to what i like and just turn shower/faucet to the hottest setting in winter or lower in the summer.

My heater only heats while water is flowing through. Otherwise it cools down.
This may have consequences not killing things that like thriving in warm water.
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.
Inline heating is pretty safe to do that, aye. I'd worry about listeria in a tepid storage tank.
