Fair point about the Python, but most of the traders can be made tanky enough for those honeypot CGs.
I fly my CM3 a lot as well (probably still my favourite ship, only got the one though

) and gank squads don't get close. They have the speed to outrun anything they can't fight, although a reactive hull with thermal resist mod will always help for when the shields are dropped.
CM4's are trickier for sure, but I'd say you'd be very unlucky to get a squad away from the focal points like CG's, Shinrarta, new finds etc. I've certainly never been interdicted by a squad away from those focal points since premium beta. So if you make the choice to go there then you take the risk and setup appropriately, but then I'm guessing you probably wouldn't go there with a mining or pirate (npc I assume) setup?
If so you'll only ever be dealing with a single attacker and as per Rinzler's video they are fairly easy to avoid. and actually, in my experience, very rare.
