Hi, I'm using Fiona from GeoPandas, actually there is the append mode, but if the data we want to append has columns that does not exists will fails. I'm constructing a big gpkg file but I don't have a way to know all the columns beforehand.

  File "fiona/ogrext.pyx", line 1280, in fiona.ogrext.WritingSession.writerecs
ValueError: Record does not match collection schema: dict_keys(list_with_column_names)

Thx!

I think this could be possible for 2.0.
