So what do you consider the length of the example deep list, is it
two, three, or six?  Length implies a particular dimension, which is
naturally the ordering of the outer list.

Scheme considers:
(length '((1 2 3) (4 5 6)))
=>
2

Yes but, why do you want to know that?  Isnt what matters whether a
particular key exists or not, and what is its value?  This is the
primary purpose of hash tables, no?

The number of active bindings in the hash table is really just a book
keeping detail.
