What will the naming be for plugins that are not ecosystem ones and they just add features to other plugins?

plugins {
    id("org.jetbrains.kotlin.ecosystem")
    id("com.example.kotlin.***")
}

Would it have that structure?

***

can be

feature

or

features

?

I would name it

features

because you will add more than 1 feature :D also the kotlin ecosystem has the (confusing) name:

org.jetbrains.ecosystem
