The group() target documents that it takes inputs and sources, but ignores them?

[Aaron Wood]

The documentation for the group() target documents that it takes all the general target variables, including `inputs` and `sources`, yet AFAICT, ignores them completely (but they get marked as used, so they don't trigger the unused variable error).

Is this a long-standing bug, or an intentional behavior?  Or a now-intentional behavior because it's a long-standing bug and fixing it would break users?

Thanks,

Aaron

I'm not sure, but I think there are cases where you want to use group() as a kind of fake or dummy target that doesn't do anything, and in this case you want those variables to have the behavior they do. 

But I could be misremembering or projecting :).

The way we handle that in the Fuchsia build is we just make a group(), and don't forward those variables, and then mark them not_needed().  Such as our templates that try to "automatically" change toolchains with a group, and then define the "actual" target in a different toolchain than the template was first instantiated in.
