Keep also in mind though, especially without the SDK, the differences between FO3 and FO2 skillsets.
FO2 had a lot more skills overall, for one, that Fo3 doesn't have. Outdoorsman, Gambling, Pickpocket, ect. Many of those skills have been homogenized together(Sneak, Pickpocket for example, work together). Outdoorsman wouldn't have as much an affect anymore, except maybe if random encounters were incorporated into fast traveling, since there is no 'overworld' map anymore.
Also consider, FO3 skills are 100 points max, while FO2 were(300% I think? Or was it 200?). Of course, skills past 100-150 were questionable, but you see my point. To be remotely proficient in FO2 with a gun you needed at least 100 to get some good shots, or 100+ if you want to aim for the eyes reliably and what not, at any sort of range.. Skill points were very sparse in FO2, with so many skills and not many skill points to work with.. Compared to FO3 anyway.. You might try to think of 15 skills points in FO3 carries the weight of as many as 30 or more skill points in FO2... Then of course, don't forget comprehension + skill books in FO3.. 2 skill points per book with no diminished returns is like 6 skill points in FO2, but in FO2, there were far more scarce. They practically litter the terrain in FO3.
So.. TLDR, Skill points are already proliferic in FO3, I don't see them needing any more bonuses personally. Actually, the double skill point gain rate is sort of a buff, despite the removed skill points. If a skill starts at like 20 and you tag it, it takes 40 points to get that skill to 100, instead of 80, which is basically 40 bonus points. 40 > 15. All that I mentioned also explains the need of the nerfing of skill point gain down to 5+INT.
