-append is supposed to work with several layers too.

I've just downloaded 
http://kartat.kapsi.fi/files/maastotietokanta/kaikki/etrs89/gml/K2/K24/K2433L_mtk.zip 
and tried your below command, both a non inexisting mtk.gpkg, and one created 
with it, and it works as expected for me.

Perhaps the bug only triggers with some initial content of mtk.gpkg ?
