It almost certainly won't come up much, unless you have a tight downtime schedule. But it's not exactly expensive, so it's not a huge risk if you pick it. It becomes potentially more useful if you are on a team with a lot of drones and/or wireless-enabled cyber. Should you ever get something bricked early into a mission, it can be useful to minimize time spent which is always beneficial.
Though I have not run many games with hacker enemies, so it's hard to say. In the stereotypical extraction, enemy hackers only deal with your hacker in the Host, and thus your teammates are not often targeted. In another situation though where one semi-competent ganger with an Attack dongle can fry your Street Sam's cybereyes, I'm sure it'd be nice to have. But it is definitely not something every, or even most, matrix-specialists need.
