Nobody has said anything about lame. The issue is that you don't 
need to know of "version1" on the C++ side. One purpose is to use 
the "inline" as a switch, so that you can use macros to turn on 
and off different library subsets. "inline" is injected in front 
of namespaces that are to be accessible in the parent, and that 
injection can be done by a macro.

But on the D side you need to know of "version1" if D does not 
parse C++ headers. Which is a maintenance burden.
