The opposite Hacker design Question, Are most of the skills needed? Options

[JoelHalpern]

Most folks complain that the lack of using attributes in RAW hacking means that hackers don't need Logic.
But as has been observed in other threads, skills are expensive in 4th edition.

So, looking at the rules, Hacking, Cybercombat, Computer, and Data Search are all allowed to default.
So, if you have a Logic 5, and 2 levels of cerebral booster, you can effectively have all of those skills at 6 for no additional expenditure?
And if you use an Agent for basic EW tasks, then whether you need Hardware and Software at all depends upon the character concept, not hacking?

(I haven't decided if this is a good thing, or a bad thing. And it appears to apply almost equally to Technomancers, except that they need software for Threading, and may not be willing to lose the resonance to the biowear.)

Does this match other peoples understanding of this aspect of RAW?

(This leads to the idea of someone who at start buys 6+2 logic, and is better with those skills than anyone who actually uses the skills themselves on the Matrix. That's why I think this as the opposite of the usual concern.)

Thank you,
