[QGIS-Developer] External providers in QGIS

[Victor Olaya]

I dont see the advantage in having providers in core. And if there is an
advantage, it's clearly not in how easy it is going to be to maintain the
plugin. If the people responsible of a given backend (like OTB) are going
to maintain it (which makes sense), why putting it in core where they don't
have write access? Better in a separate repo. Also, they can release
whenever there are changes, without having to wait for a new release. That
way, the plugin will always be in sync with new releases of the backend app.

If we put them in core...why putting only this big ones (which in some
cases require installing external apps manually by the user), and not put
other plugins that exist and contain Processing providers?

I thought the idea was to not have core plugins and avoid them if possible.
I don't see why we have to treat plugins that have Processing provider in a
different way. Specially considering how easy it is to install a plugin in
QGIS.

Cheers
