I think you do Boulez a bit of disservice. It was him after all who said that Schoenberg was "dead"; meaning obviously that his use of the method was no longer useful (and therefore it's tonal implications). It may be precisely because modernism has emancipated those dissonances that composers can now use them to create structures rather than to create shock. I think really only very few composers actually went out of their way to use dissonance to shock. Ives and Cowell certainly, beyond that I'm struggling to think of another. Except of course film music which regularly assoicates "shocking" images with dissonance.
Boulez does create controversy. I read a biography of Ligeti recently in which he said he did not much like Ravel, no one bats and eyelid. However when Boulez points out for example that Shostakovich brought nothing new to musical vocabulary then (and as with your Tchikovsky claim) people start getting excited.
Also I'd take issue with you over the use of consonance. It's not as if consonance in music went away, it was after all used in pop music and in minimalism. So to hear "pure consonance" (as in the early Tintinabuli pieces of Part I suppose ?) in itself does not reveal anything especially new.
Lots of composers today feel the very distinction between consonance and dissonance is outdated. Perhaps assuming a piece which uses dissonance "is out to shock" is a 1920s way of hearing, rather than opening your ears up to new structures and new ways of hearing.
I'd be intrested to hear your thoughts.
