I will write individual pipelines for most of the common use cases,
taking care to use only plugins that are free software.

I do not plan on using playbins or any other elements that will load
plugins dynamically.

The user will not.  I don't want to make Emacs a tool that is more
convenient when used with proprietary software.

In short, I don't want Emacs to lead people who judge by convenience to
use proprietary software.
