I can see your point with some redundancy between code and documentation, but the bbdev.rst documentation is arguably clearer as it is : the detailed information in paragraphs puts into context some of the information captured in a nice and concise table. Clearer than having to go back and forth in doxygen capturing some of this in a less compact format (which still has its own complementary value). Matter of opinion, let me know if you have a fundamental concern with keeping such table in that document. 

I am not sure it is clearer to document all parameters in rst.

The main concern is about maintainability.
When we change something in the code, we change the doxygen
and we forget the rst guide.

The other concern is that maybe the doxygen is not complete.

My advice is to reference the doxygen when the information is the same.
