It hit me that I didn't provide a full debug-loglevel debug with 
everything custom disabled. So I created a bugreport at 
https://bugs.freedesktop.org/show_bug.cgi?id=89442. Please do tell if 
there's anything else I should provide.

Any tips for what I'm missing here to create a workaround making 
systemd-networkd not consider can0 as a network device would also be 
appreciated :)
