IMO, connecting radials to the rebar in concrete slabs and foundations is a good thing.

There's confusion here. The purpose of radials is to SHIELD the field produced by the antenna from lossy earth, NOT to CONNECT to earth. The intent is that the field couples to the radials and NOT to the lossy earth. So -- unless the radials are for a grounded tower, it is NOT a good thing to connect radials to the tower base. N6LF has also observed that connecting radials to ground tends to make radial currents more unbalanced, which increases ground losses.
