I think we have only two means for keeping schema.org useable for a large audience:

1. Modularization, i.e. at least make a clear separation between 
a) the meta-model and architecture of the vocabulary and
b) the domain-specific parts

but maybe even further,

and

2. Strive for a self-contained, frame-based organisation, i.e. reducing the relevance of the type hierarchy, eventually up to a point where we (publicly) just have a flat bag of types and associated properties.

That does not mean we abandon the hierarchy internally; it will remain useful for managing the vocabulary.

Currently, users and people who want to propose extensions must understand the official and inofficial parts of the meta-model and memorize the type hierarchy.

See Figure 4 in this paper:
