I would say not, because, while of course cooldown reduction is great, you can actually reach 40% already with 5% from masteries, 5% flat glyphs, 5% scaling glyphs, 10% Brutalizer and 15% Ionians.

And in the endgame, when Brutalizer and it's upgrades aren't worth it (because don't deny it, both items are pretty mediocre on Riven), you can put an Infinity Edge or some stuff like that in that slot and buy a blue pot to be at 40% cdr anyways.
