It's already now possible to work with multiple QgsProject instances side by side. So it is not a singleton by definition, since the constructor is not private. There are still some parts of the internals that use the method QgsProject.instance(). These calls need to be reworked in order to be able to continue the work on an API like you propose.

| Oct 14, 2018 at 7:32 | comment | added | Matthias Kuhn | @MickeyPerlstein you are right, if you use QgsProject.instance() it's not solved. However, standalone apps can already now be implemented with multiple projects and the QGIS server code is moved in this direction too. In the long run QgsProject.instance() might completely disappear. | |
