Adapted lenses, why can't I use a lens module that is in database?

I’m having an issue, being a Panasonic S1R user. On the Panasonic S1R, the only supported lenses are from Panasonic, even though Sigma and Leica produce a great number of lenses, and there is an adapter that most people will use to at least adapt some lenses from Canon EF. For instance, I am missing the native L-Mount Sigma 35 f1.2 and Sigma 14-24 F2.8. In addition there does not seem to be any way to apply lens profile for my EF lenses: Sigma 85 F1.4, Sigma 70-200 F2.8 C, Sigma 150-600, Sigma 120-300 F2.8. Could there at least be a way to use my Canon EF lenses with a lens profile from Canon??
