First, some context. I own pretty much all of WFRP 3e, but must admit to only having one short campaign of actual play. I've played Edge of Empire but didn't get the chance to read the books extensively as another player in our group was a hue Star Wars fan and bought them all.
Having played bothe WFRP 3e and Star Wars, I personally found that the Advantage / Threat mechanic was much more mechanically satisfying in WFRP as every ability had it's own short table of ways you could spend those symbols. I know the Star Wars implementation seems hugely more popular and Genesys seems to be closer to it than WFRP.
I'm not calling for a return to decks of abilities (though that would be cool; and even more tricky to do with a generic game) however it would be great to have tables of mechanical effects for different types of common endeavour that happen. A good example I am thinking of is Stunt Points in the AGE RPG line, where there are short tables of things you can spend stunt points on for combat, spell casting and to a lesser extent social and exploration activities.
I'm hoping this is already in the Genesys system but if not please could the Devs think about it? It doesn't take anything away from pure story-interpretation of Advantage / Threat whilst adding a bit of mechanical crunch for people who like that kind of thing.
