This is getting common in Denmark, I think due to two reasons:
1. It's very common for students to work 1 or 2 days/wk while in university, so companies (esp. tech companies) are already set up for it. This is because the way university funding is structured students have an incentive to work ~5-15 hrs/wk, but cannot work more than 15. Some stick with the same arrangement even after they graduate, working 15 hrs/wk to fund a startup, or game company, or whatever.
2. Since benefits (healthcare/childcare/etc.) are provided directly by the state, not tied to your employment, part-time vs. full-time doesn't matter from that perspective.
