It might be nice to have the ability to group apps together even if its only a GUI abstraction.
I can also see this being useful within private networking rather than starting a new “org” for every “project”. An example would be an org for a consulting company, might be nice to make sure that a group of apps for each client are secure within their own network.
Again, the main and lower hanging fruit here might be to have app groups for simple use cases of projects having a app server, postgres app, etc.
