The advantage would be interconnect energy and performance.

To an extent this has already happened with wafer scale integration, e.g. cerebras.

The problem is the increase power usage of the additional caches that are necessary - modern CPUs already need a bunch of physically local caches in addition to the large L1/2/3/n caches because of timing of flowing electrons from A to B. At some point the benefit of larger single die becomes minimal. The moment that happens you benefit from making separate chips because of increased yield.
