I have not been able to find any restrictions on the border crossing by foreigners on the Kartsakhi.
Actually the most news on the subject I was able to find on Russian and Azeri news sites specifically with respect to the high speed rail project Baku-Tbilisi-Kars (Russian) where Kartsakhi would be the border crossing station for rail traffic on the line.
On top of this Kartsakhi is being viewed as a means to improve tourist flow into Georgia (Russian), so I don't see them imposing the restrictions on foreigners entering the country to locals only after it's fully open given this view.
