Here in Romania we use Type F but sometimes also install a modular Type L socket alongside regular ones because it's smaller and you can fit 2 of those in place of a full Type F/Schuko one. We don't use Italian plugs and so only use them for europlugs (max 2.5A and double-insulated so no ground needed) (Kind of something like this)

I do find it kind of sad seeing them getting slowly replaced even in Italy (I know it won't fully happen of course) because they're very space efficient

Now really imagine what would happen if Americans tried to switch to metric.
