I think the key word is "non-trivial". Diversification is still present, just non-trivial. most path more or less have some and it's definitely non-trivial.

Diversity summons are mostly combinations of high research, high cost, cross path. Death's diversification specialty definitely have these elements in spades.

For example, Spectral mage, which can be verrry expensive rolling paths you need for a relatively low path level. The hiddens are all cross path and a bit out of the way. Tarts which are probably foremost in people's mind is both cross path (nature), end research, and somewhat expensive to get paths you want (all them restore soul and rolling good titans add up). Still, I see that as death's specialty, raising the dead with knowledge of other paths.

That's one aspect of dom3 I really like, that the 8 paths are so diverse from each other and each with useful/meaningful specialties of their own.
