Drive v3 lacking support for Apps resource

Any ETA for v3 feature-alignment for `apps` resource as in v2?
https://www.googleapis.com/drive/v2/apps

ref. https://developers.google.com/drive/api/v2/reference/apps
> The apps resource provides a list of the apps that a user has installed, with information about each app's supported MIME types, file extensions, and other details.

v2 code reference:
