Good summary.
2. Terminology. Both a 'Core Aggregatable Address' and a 'Scoped Address' use an 'address' in their definition while the address itself remains undefined.
There are three Entity Identifiers. Would it be enough to have just one global identifier for a point of connection to the network (a node if there is only one interface, an interface if a node has more than one). Also a definition of a 'Communicating EI' equals to a 'Scoped EI' when binary is used for the later. Would it suffice to have a single global EI with the scope determined solely by the locator?

3. New Math or New Naming. Mapping combines split attempts separately from geo / AS aggregation. Why / how does aggregation prevents the splitting? E.g. in a split the network (locator) part still can be aggregated by geography or AS.

4. Divide and Conquer. Why consider 'Identification by name'? DNS is a limited subset of the Internet where a human-readable name is needed. The majority of network elements remain transparent to a human end-user of the application.

4.1. What mappings? Why mapping is needed is there is a split, i.e. an id part is added to a locator part to establish a routing end point?

5.3. Separate Identification. Why the oversimplified form is not good? If it is insufficient, what is lacking? If it works, what benefits are gained by adding complexity?

6. Scoping. The 3rd paragraph is confusing as it refers to the scope of identifiers. The scope is a property of a locator, right?

Thanks,

Peter
