Just a little advice - we need to push people toward the standard widgets
for these, eg QgsFieldComboBox, QgsMapLayerComboBox. Reimplementing then
with new Python versions isn't a good idea, since it breaks consistency
with core (and is also a lot of extra work!)

plugins are useful but we can't use them in batch mode or in complex
workflow. Moreover, they often produce only shapefile.
