Interesting this information is not more widely communicated. Begs the question why,,,
With a tankless the water before the heater is at well temperature, and after the heater is at set temperature... both those should be outside the range for bacteria to grow at any dangerous rate.

At best, the piping leading to the tankless sitting long enough might reach ambient temperature... so a warm period might make it to the lower threshold... but once being heated, the bacteria would die.
