Maybe it would be enough to only support PG_MODULE_MAGIC (without 
arguments) in C++ for now.

That would still require removing the named initializers inside 
PG_MODULE_MAGIC_DATA(), but that's only an internal change, and it would 
not affect C-language users of PG_MODULE_MAGIC_EXT, and we wouldn't lock 
ourselves into a particular style in C++.

Then, maybe in a couple of years, when C++20 is more widely available, 
we could enable PG_MODULE_MAGIC_EXT for C++, or design an alternative 
construct for C++.
