Python applications that are also libraries

[Ricardo Wurmus]

Hi Guix,

we have a bunch of packages that are used both as applications and as
Python libraries.  An example is “deeptools”.

As a library we need to propagate other Python inputs; as an application
this is not necessary because we have wrappers.

I wonder how to deal with this.  Should we assume that these packages
are used as libraries and default to propagating all Python inputs?  Or
should we have package variants (or outputs?) that propagate inputs as a
side-effect?
