Operatives and Insight Bonus

[bookrat]

Please find something wrong with this:

1) Insight bonuses don't stack.
2) Operative's Edge grants an insight bonus.
3) Operative Specialization grants Skill Focus, which is an insight bonus.
4) By level 7, Operative's Edge makes the skill focus obsolete.

Why bother even granting Skill Focus if it's going to be obsolete by another class feature several levels later?

[SGPB]

Skill focus let's them take 10 on those skills while in combat with one of the operative abilities gained at level 7.

Because Operatives get this class feature at level 7.

Specialization Skill Mastery 7th Level

You become so confident in certain skills that you can use them reliably even under adverse conditions. When attempting a skill check with a skill in which you have the Skill Focus feat, you can take 10 even if stress or distractions would normally prevent you from doing so.
