No, I wouldn't say it was atypical. If you follow my link at the bottom, you can have a look at my collection of German glass and Peill in particular to show you some examples - I have a lot of clear German crystal pieces that are quite thick-walled, and they also did irregular shapes, like iceberg type vases in the (I think) 70s. Some German firms like Rosenthal also employed Scandinavian designers, so the style distinctions tend to get blurred that way. Partial frosting I've seen mostly in German designs (and a bit in French designs but I really don't have a clue about French glass).
But - I'm not at home enough in Scandinavian glass to firmly point at the German possibility over the Scandinavian options. If it is German, however, and completely unmarked you basically can only wait until someone else finds a labeled one at some point. There were a lot of different factories (most closed down in the 80s or 90s), and not much documentation survives.
