Thanks to the QGIS Grant 2019 program, we (myself and Nyall Dawson) have developed a new QGIS core API, fully exposed to Python, that makes it possible to manage stored connections to various data provider source in a unified and consistent way. For example, there is a Python class named QgisInterface that acts as a wrapper around a C++ class of the same name. The issue does not appear to be that I have failed to import some Python package automatically imported by the QGIS application (qgis.core and qgis.utils) - I have those import statements in my standalone script, along with all the other package imports the script requires. It achieves this by using the 'QGIS' Python API via the command line. The QGIS system itself is written in C++, and has its own set of APIs that are also written in C++.
