Having done a close read of regfile/virtual_port.py (apologies for
giving a "terrible name for a complex register"), and reviewing the
yosys show top logic diagram I think I mostly understand what's going on
in this module.

Regarding the "global" thing, are you referring to the self.wr/rd_ports
"for external use"? We should instead just use the existing methods on
RegFileArray to set up the external ports? How do we go about not
letting anyone access the 8 reg-ports?
