I don't think I'm not confused. However you seem to be missing my point.
Yes it wasn't removed and because it was _not_, it tends to show that
it's not necessary nor helping to _remove_ it. That's an argument in
favor of _not_ removing libamr wrapper for WB encoding.

I completely understand what you are talking about, and IMHO issues
should be dealt in the name of FFmpeg, the project, if you wish you
include yourself and I wish to be included as well, I think you should
use "us".
