You are reading too much into this.  No decision was made at all. 
The default chosen by the C++ front end is

#define BOOL_TYPE_SIZE ((SLOW_BYTE_ACCESS) ? (POINTER_SIZE) : (CHAR_TYPE_SIZE))

To change it now though would break ABI compatibility.  If people
care so much, it could perhaps be keyed to -fnew-abi.
