Yes, that is a recipe for success :)

I will do things like the following to make the
explicit ports in the top-levels easier to manage

     def my_core_top(
         # somewhat painful explicitly listing the ports
         # ...
     )
     portmap = dict(clock=Signal(bool(0))
     portmap.update(axi4lite_portmap)
     my_core_top.portmap = portmap

In my testbenches and conversion scripts I don't
need to type out all those ports again

     portmap = my_core_top.portmap
     clock = portmap['clock']
     axi = AXI4LiteInterface(portmap)
     tbdut = my_core_top(**portmap)

To me this makes sense because a top-level maps to
an explicit static hardware device, having tools to
map the explicit portmap to the generic interfaces
is a good approach, in my opinion.
