It’s the same in any country with buildings over 100 years old.
In here 100+ year old houses are pretty common but practically all of them still have at least somewhat up to date electrics with that 3-phase input. It’s been around for decades after all. My house is built originally 1928 and my mothers house is from 1909 and both of them have 3x25A main breakers with those 380V 16A CEE sockets around.
And as garages commonly double as a work space with 3-phase induction motors on the tools it’s still pretty common to have that 3x16A available as it’s not that much more expensive to pull 5x2.5mm² cable to the garage compared to 3x2.5mm² for single phase 16A outlet.
Also, it’s typically not that expensive to upgrade your panel, if you live in a zoned area. Buildings in the unzoned area typically have good electrical connections since in the countryside you typically want access to three phases.
Of course there’s then the need to upgrade the panel as well, but that’s a relatively simple operation.
My childhood home had 3x90A breakers since it originally had a resistive heat setup, in a relatively large building (plus some other energy intensive equipment housed there). In reality it was far too much even then, the max load we calculated under full load was more like 25-30 kW.

As an example for moving from older single phase service to 3x25A, it costs around 810 € typically, with 2000-3000 € as a worst case scenario. That’s in Lahti, Finland – in Espoo it seems to be around 500 €
