How bad is this rust?, rust spotted in hell hole on another "rust free" car Options

So I've recently looked at another 914 for sale. It's a very nice car on the outside, but when the owner told me its completely rust free of course I was suspicious. I found two small holes in the hell hole area. Generally, the underbody of the car is solid and the door gaps are good.

Attached are some pictures of the hell hole area which is the only rust I could find. I have not seen the longs with the rockers off, but I did get under the car on a lift.

Image 1 - the hell hole from the top
Image 2 - looking at another spot, below the hell hole from under the car.
Image 3 - Not sure if this helps, but it is a shot behind the rocker on the passenger side.

Assuming there isn't any more, is this rust a minimal repair? Would cutting out around the two holes and welding a small patch be a good repair or would it take more work? Note, this is not meant to be a project car, but some repairs are OK.

Looks pretty typical. I would say you could patch it pretty easily once you found the extent of the thin metal. Expect to have to patch the right side vertical piece as well.
