I was just pointing out there is little benefit to the Scholar tree that does much for someone who just has a decent intellect and a point or two in the skill.
I think this is a bit subjective - as previously mentioned, realistically this is the same for every skill. I see what you're saying about knowledge checks, but if we go by the CRB, success gives general knowledge about something with Adv reducing the time it takes to figure it out (If I'm mistaken correct me as I don't have the book with me). The more successes, the more precise things get.
Here's an example: Let's the you give the group an objective is in the Outer Rim, if the player rolls one success no advantages on the roll, they'll figure out that the objective is in Hutt Space, but it may take them the entire day to figure that out. The player would need to dedicate game time to research the objective and where it might be, scanning the various literature on the Outer Rim looking for something specific. Let's say that character rolls an advantage, he'll get the same level of Knowledge, but faster... Maybe it takes him 6 hours... Now, if he generates more successes, he may find out that it's located in the Rorak sector, more successes, Rorak 5, more successes a certain Hutt has what you're looking for, more successes he's located here, more success, here's the defenses. Yes, it's a bit of a tedious process, but that's the way Knowledge, as written seemingly works (beyond the basics like adding/removing dice).
So, taking that into consideration, a Scholar will be more proficient at finding things, faster than a PC with high INT and a rank in a Knowledge skill. At the same time, any specialization can arguably do what your saying with any skill. A high agility Pilot can shoot a Blaster just fine, without any ranks in Ranged (Light) or Ranged (Heavy) - will they be as good as a Mercenary Soldier at killing things? No, but they can still cause damage. It's vice-versa as a Mercenary Soldier can be a decent Pilot with 4 AGI and no ranks in Piloting as well. To be honest, the Piloting skill is a bit ambiguous with Extra Successes and Advantages as well outside of opposed checks - if you make a successful piloting check, you're rewarded with not crashing. Extra successes and advantages give way to what can improve the vessel or how the pilot can do that particular situation better, which can be done by a Mechanic or high INT. Heck, even a 1AGI Trandoshan can fly in ship-to-ship combat with the only real drawback being sucking at Gain the Advantage. Fact of the matter is most PCs can do A LOT of general things if they have a high characteristic, and succeed, it isn't just knowledge. Talent trees provide a means for players to do a handful of specific things better.
If GMs don't want to use Knowledge skills because they don't fit in the type of game their running, or the players aren't interested in using them, its understandable. But equally, if a GM and players want to run a game based off knowledge skills the way they are mentioned in the book, the skills are available as tools for that type of system. While the latter may be 'boring' for some, others enjoy that style so I don't think there's necessarily a right or wrong answer here regarding skill use, other than to say that its going to depend on the game.
