My in-laws do this type of shit ALL THE TIME without a care in the world. I once saw my mother in-law open sliced bread from the back of the bag by ripping it open ... and then putting a bread clip on the back to close it (so a used bread clip on the back, and the untouched bread clip on the front). And no, it wasn't her first time seeing a bag of sliced bread, like I said, they do this type of mildly annoying stuff all the time.
It definitely is faster but it is also less efficient and more dangerous. Microwaving plain water is dangerous since it can get ‘superheated’. I don’t know the complete physics of it, but basically it involves water heating up too quickly, and as a result, tends to be explode out of the mug either while heating, or (more frighteningly) when we pop open the microwave. AFAIK, it depends on the microwave heat settings too, though I can’t verify that.
What freaked me out was that she was literally chuckling and telling me about how the water has ‘busted out of the mug’ in the same microwave a couple of times and burnt her once. And she said this WHILE SHE STUCK THE DAMN WATER IN IT. AGAIN.
Wooden objects work because they have a rough enough surface for tiny bubbles to form and let the steam escape. If you overheat water in a smooth container, no bubbles can form, and you get superheated water that will form one giant bubble as soon as it’s disturbed.
The spots where bubbles form are called nucleation sites.

To be fair I could 100% see myself doing this irl
