Yeah, you may be right. IMHO it also could depend on how much SJG approves the unofficial ruleset. Right now the official logos for GURPS and Dungeon Fantasy are implemented as decals, which is meaningful and promising.
On the other hand, if they want to see more GURPS games around, the availability of some of these features (most likely already existent in non-distributable extension files) without requiring extra homework to the users could help.
Now, as it was said there's the need of evaluating what I think are several factors, so I guess we'll see! Regards
