To be honest I am a little bit confuse with the examples you mentioned. I do not see where the grammar is now defined in the .cpp file from the example. I only see a declaration of grammar in .hpp.
I would have expect that the Grammar header is defined in .hpp but the actual EBNF definition is defined in .cpp. Hence, I do not see example of (2) in the examples, unless I miss something.
About your point (1), I think Classic Spirit also support this. You can have a rule that embed a grammar which is defined in a different file.
