Considering following two reasons, I'd like to suggest reassigning pattern number pf* for Friends and Disney Princess, in addition to current "Fabuland and Scala".
1) Friends (2012-) and Disney Princess (2014-) are some of long-lived themes currently in catalogue but there are no pattern number range is assigned.
2) Fabuland and Scala were discontinued quite some time ago and almost all patterned parts have been authored, so it is likely that pattern number pf* remains empty for modern parts (87079 etc.)
