I transferred from a MAA-CDG flight to a CDG-LHR flight at the end of August and walked (didn't realize there was an airside shuttle at the time.) The immigration officer didn't stamp my passport, and when I went back through immigration to get to my connecting flight, the officer there checked my name off a list. So it is possible to transit landside at CDG without entering the EU.
Still, it is a horrible, horrible airport. I needed to find the post office and a friendly information person told me it was right down in the next terminal—which ended up being about a 15 minute walk (and I walk fast.) Would've just held onto the letter if I knew that since I had a fairly tight connection!
