[QGIS-Developer] Keeping OTB algorithm in qgis processing

[Paolo Cavallini]

Hi all,
sorry, I miss a point here: we have a dev who volunteers to maintain a
piece of code. He is quite credible. His proposal minimize the overhead
to QGIS code, and moves much of the complexity to an external sw.
Why do we suggest to keep him out of the door?
All the best.
