This is the expected behavior.
Airflow adds **an additional 3 directories** to the variable `sys.path`.
* ``conf.get('core', 'dags_folder')``
* ``conf.get('core', 'airflow_home')``
* ``conf.get('core', 'plugins_folder')``
This means that plugins and DAG can use imports that match the current
directory relative to each other. Otherwise, the plugin would not be able to
load another file that is in the directory next to the plugin or DAG so that it
cannot load the file that is next to it.
In Airflow master you can check the content of the sys.path variable using
the airflow info command.

The problem is only the lack of description of this behavior in the
documentation. However, I am already working on it in my free time. The first
step is to add the airflow info command because I need it to describe this
behavior accurately.
I recommend not using plugins to add new operators. This is problematic
behavior and causes various problems, among others increased RAM consumption,
slower task startup. It's best to load operators as if they were normal python
modules. Ideally, it would be a separate package installed by pip or added to
PYTHONPATH.
