Basically, another big problem with infiltrators is that it's a high-risk game even to get to the skill levels to actually play the intentional high-risk infiltrator game.
That's precisely the problem the above is intended to solve: give low-skill infiltrators something worthwhile to do besides sit and train at the Academy, without a near-certainty of getting caught and banned.
Perhaps I didn't state it clearly enough, but I
do think that it might be worthwhile adding some other infiltrator actions that don't (individually) do a whole lot, but do give you experience, and have very little risk of getting caught.
Not sure what yet, though.
