 All feedback gratefully received!

The PEP does not seem to specify how handler are retrieved by their
name/id. How should this work? Especially given the statement:

The handler name lookup dictionary is for configuration use only
 and will not become part of the public API for the package.

thanks for incorporating these changes.

What I mean by this is that, if you specify some handlers in the initial
configuration:

handlers:
  console:
# configuration for a handler
  file:
# configuration for a handler
  email:
# configuration for a handler

then internally, there will be a map which has keys console, file and
email pointing to the respective handlers. In a later incremental call,
you can do

handlers:
  console:
level = ...
  file:
level = ...
  email:
level = ...

and the levels will be set on the handlers previously set up with the same
ids.

If you set up handlers programmatically and give them names:

h = logging.StreamHandler()

h.name = console

this will add an entry to the map with key console and a reference to h as
the value.
