It is more complex than that looks like....(i am just trying to fully understand how the things work...).
There is
1.) the Gantry component that provides the framework ...
... that is used in ...
2.) the Gantry template – wich is a basic boilerplate-template for developers
Nothing merged.
So, if it is not merged one should presently see the template boilerplate-template in the template manager.
Thanks and regards,
