Are not all built-in script open-source ?

[triiif]

For exemple where is the built-in Novation Launchkey Mini controler script ?

I have deleted the whole folder /opt/bitwig-studio/resources/controllers/

but a few scripts are still there if I open bitwig.

I don't get it Is this one not open source like the others ?

The built-in script is pretty nice but i want to add a way to stop a clip.
