Routing back to intake is the best way IMO.
The only thing you really shouldn't do is vent it to atmosphere as its metered air....although it is a small amount.
It's the same thing as the top port on an ext wg. Some people hook it up, some people don't.
I think I know what you mean, but that's not the best analogy because in an EWG, the two ports do not intersect internally. They are on two opposite sides of a diaphragm. In an EBCS, the two exit ports are directly related to each other.

If you want to open the wastegate more, you reduce WGDC which diverts less to the inlet and more to the WG. Otherwise the pressure gets diverted to the inlet pre-compressor and whatever slight pressure loss you have post compressor, translates to a pressure gain pre-comrpessor. Running it to the 'inlet' really is the most optimal way. Period.
