Having a complete keymap at the disposal of third-party libraries means that there are (at least) 26 letters free; each of them can be bound to a separate keymap.

That's still much less than what can be bound to several such prefix keys.


That's wrong, both from a practical and from a theoretical point of view.

From a practical point of view, the bindings in (B) are not deeper/longer
than the bindings in (A):

|      (A)      |      (B)      |
|---------------|---------------|
| C-x j         | C-o j         |
| C-x j = f     | C-o j = f     |
| C-x j t . % + | C-o j t . % + |
| C-x 4 j       | C-o 4 j       |
| C-x x :       | C-o x :       |
| C-x x t e     | C-o x t e     |
| C-x x t + b   | C-o x t + b   |

From a theoretical point of view: the number of available keys is, in both
cases, aleph-zero.


No argument for how you can put lots of stuff on a single prefix key can overcome the fact that more prefix keys give you more than does one prefix key.
