[QGIS-Developer] Understanding plugin management in QGIS: Meta data fields

Hi Etienne, Nyall,

thanks for your replies.

Ok, this makes sense. I just tried to trace the use of this flag and -
as far as I can tell - it's only being looked at in
`QgsPythonUtilsImpl::pluginHasProcessingProvider` in
`/src/python/qgspythonutilsimpl.cpp`, which is not called at all (as of
today's master, at least). So just to be clear: The flag is not being
used *at the moment*?

With respect to my last remaining question:

> I understand that `id` is *the* unique identifier for a plugin.

What's the story behind `zip_repository`?

Best regards,
Sebastian
