I've read, I know this wonderful technology. Even I use it every day. Do not change the fact that I disagree with this naming ...
It's like an energy-efficient light bulb called the 100W. When it really is a 36W (100W equivalent)
For light-bulbs, the power label tells you how much power is drawed from the mains. A small percentage of that is converted into light, the remaining is heat. As long as most light-bulbs were based on the same technology, the label worked, because one would know that a "100W" lightbulb actually created 10 Watts (or something) of light.
When technology changed, and much more efficient light-bulbs appeared, what should one use to inform the public? I actually think that it makes sense to label it as consuming 8 Watts, but producing light comparable to e.g. a "60W light bulb". Over time, candela or some other light measure should be used.
A properly multisampled image sensor can create an image consisting of e.g. 200MP of discrete image points. Therefore, I think that 200MP-ms makes sense. Over time, I would like to see best-case lp/ph MTF50 used instead.
