Hi Rashad,

let's move this discussion to QGIS dev list.

Seems there is a misunderstanding here. Description files is a pure-Processing
thing, GRASS does not ship any description files, they were created by
devs and users and updated when necessary.

As I understand, your idea is to move description files to the OTB disctribution
and have some settings in the Processing to point to these description files.

I was talking about OTB plugin. For example, if you may found and fix a bug
in the plugin or implemented new feature to support new OTB functionality.
If plugin integrated into QGIS you will be tied to QGIS release cycle.

Next QGIS version will be 3.0 and according to the current roadmap [0]
