Most people aren't trying to speed-shift. Hell, a 5-3 downshift on my old 951 (160,000 miles) doesn't even strain the synchros. There's no undue resistance, and there's certainly no grinding/groaning sound.

I have never, not once, encountered a situation on public roads where you need to rush a shift that much. This isn't the SCCA runoffs we're talking about here.
And your analogy does not stand. Failing to rev match and simply taking the clutch up slowly causes excessive wear on the clutch lining. Synchros are sufficiently durable that one needn't worry about wearing them from shifting too slowly. In fact, you put less strain on the synchros from shifting slowly, whereas in the case of the clutch, wear is increased by slower operation.
Yes, on a racetrack, these techniques have a place. But they are beyond superfluous on public roads. You just plain never need them with modern cars on public roads. You may enjoy them, you may want to use them. That's all well and good. But they are decidedly not "needed".
