Personally I (and my sons) relished thosed quotes from the Silmarillion (e.g. "die now and the darkness have thee!!")

Perhaps it was in the (unnecessary, to me at least) interest of "modernisation". though that's a mere guess.

I agree that the "archaic" language is in fact a point in favour of the UT and Silm versions.
