Obviously they are not wasted.
Yes, L-primes are wasted on a "crop-frame" camera, because one of the characteristics of L-primes - and also that which makes them more costly - is the better corner performance. Only on a "crop-frame" sensor these, shall we say, quality corners are discarded/disregarded/wasted.
One facet of a good lens can be corner performance (unless that's not what you want, e.g. 50L), but I don't know if it's fair to say that a lens is wasted because the sensor can't see the edges. I think most people using primes do so for speed. Not having zoom glass generally improves optical performance and weight too, but it's the max aperture that draws me to primes. YMMV.
But I'm struggling with why you put the word in quotation marks. Are you purposefully arguing a point which you don't believe?
Because terms like "full-frame" and "crop-frame" mean absolutely zip ... unless your point of reference is the old 35mm films and the lenses made for that size, like L-primes.
It was the quotes around the word wasted that got me curious.
