Only the simplest cases of prepending/appending staff.
If we want to splice into the normal export template, users currently
must either write an output filter or rewrite the trnascoders
completely.

The proposed template system will provide more flexibility to modify the
default export transcoders.

Could you please illustrate with examples?

This can be done with :filter-parse-tree or :filter-headline

Could you elaborate what kind of "play" you are referring to?

Currently, transcoders are opaque functions that expose a limited number
of pre-defined settings. Turning them into templates will allow certain
non-standard alternations that we cannot think of in advance. Without
directly modifying the transcoder function code.

Could you elaborate?
