I really wonder about ppl who think power waste from an led amounts anything appreciable.
It is not the LED. As you noted, that is nothing appreciable. But it is the circuit behind the LED can matters. And for sure, one or two such devices won't amount to anything appreciable either. But most homes have way more devices than that.
the PSU is out of spec if it's drawing more than 1W
If talking about the PSU alone, that is isolated, with no components attached, then I fully agree. But when installed in a computer, then depending on the attached components, it could be more than that - but not a lot more. DDR4 and DDR5 RAM, for example, consume some power during standby as, by default, the system maintains data in RAM (in a low voltage state) for fasters startups. If you have 4 sticks instead of just 1 or 2, it will consume more power. If your mouse and keyboard are designed to wake the computer, they will consume power, even more if wireless. That means the motherboard itself, while in standby is still "alive" and consuming some power.
But still, this does not amount to much. If the computer (including the PSU) demand more than 10w from the wall when in standby, something is not right.
Years ago, I had to keep nightlights around the house for the kids and grandkids when they were little. These days, I have to wear my sunglasses in the middle of the night when walking around the house due to all the illuminated clocks and LEDs.
