Fortunately, there are many other solutions for this. See the FAQ on switches to use with Hue bulbs. (This is a clickable link.)
As for what to do if the power goes out, as you mentioned, most smart bulbs including hues will come back on to full power when the power is restored.
One community member has written a smart app which monitors an individual bulb and if it comes on, it then restores all the smart bulbs to their previous state. So they do come back on, but only briefly.
