In general, initialization works just downstream the readers tree, without concireding ordering.
This cause issues in scenarious like so for ex. in module Lisp

Vpp - contains configuration
Honeycomb - config/context empty

LocalMapping customizer is invoked first(it uses context mapping for locator sets created in LocatorSetCustomizer) ,and it fails ,because respective context mapping was not yet created. This either requires ordering of init, or some separate before-init context initialization
