Different German: it is hazy, but I believe I started out with block/print letters in pre-school, and then "graduated" in some early class to cursive.

Print was more seen as a stepping stone, a teaching aide, something to be eventually superseded.

In Poland, children are likewise taught cursive from the get go when they are taught to write. There is no initial block letter stage.

No never. They taught us some type of preletters in cursive, in kindergarden, as a stepping stone to real cursive. We never wrote print in elementary school. However, the kindergarden and elementary school were catholic institutions. Most probably they are more conservative than the average in the country.
