Is webmock used anywhere inside Nucleus?

[stefan-kolb]

Cannot find any usage in the code, e.g. stub_request.
Only places that have webmock is VCR c.hook_into :webmock.
It is also not required inside spec_helper.rb

Is it automagically loaded because it is inside the Gemfile without using require 'webmock'?!
