I could live without that, but if it's implemented well, then I'd be all for it. After all, those that don't want other players to attack their base simply need to take precautions not to be noticed. Which, given the size of a planet or asteroid belt, would be quite big.
Granted, a clever/cautious killer could do so... follow at a distance, high wake scanner to find system. Following them all the way to their base would be tricky (unless the pilot being followed was oblivious), but assuming they're going to low-wake in close to their base, a pilot could wait at a distance for them to drop then follow the low-wake in to the approximate location.
Yeah, you'd get people punked and rage because they expected their base to always be safe... to them it would just be important to make them aware of basic safety steps.
Then again, how many times a week do we have to repeat the mantra "never leave dock without insurance" to people here
