I would argue that overlanding is a good bit more involved than just "off roading", and so anybody who overlands either already has recovery gear and/or needs more than the basics, or whatever would be included in a starter kit.
I don't overland, but I have an air compressor, air down tools, general tools such as wrenches and allens and pliers, etc, tow strap, soft shackle, hard shackles, rechargeable battery starter with jumper cables. I use it fairly often in the desert when responding to the recovery requests in my local FB page. Would argue that my stuff is somewhere between basic and intermediate and it's just average stuff. My point being is that the bigger items, such as treds or maxtrax for example, would be more useful for an overlander since they likely already have what i have
Edit* for the sake of correctness, I just wouldn't use "starter recovery kit" and "overland" in the same sentence lol sorry I picked apart your contribution to the thread
