khaalis, what he is doing (i am pretty sure) is a mix.
fighters (etc.), like all other classes, will get martial proficiency with *one* weapon.
Then, as a 'class ability' or whatever, the non-proficiency penalty (for martial weapons) is reduced from -4 to -0.
So, as a first level fighter, I am proficient in all simple weapons, and one martial weapon. I will pick scimitar.
Now, if I use a longsword, I take not hit on my BAB for non-proficiency. But I can only take weapon focus on the scimitar. If I want to take weapon focus on the longsword, I will have to burn another feat to become proficient, and then can focus on it.
Now, I think this will only lock fighters into picking what they want to focus/specialize on much earlier.
