Toulouse, Host and Tripartite questions marks

During the World Championship it was obvious that the selection process to the Olympics was not clear. The commentators and some media thought that Japan was going to select two athletes to the Olympics. Now we know that they, logically, will wait until the last competitions until they will choose their Host nation spot. What is also not clear in the official qualification document is whether the Japanese will be allowed to compete in the qualification event in Toulouse. This will have a major impact as they probably will have another 8 - 10 male and female qualified being Top-20 in the overall combined. If they are out, it will probably be good enough to be Top-30 to make it to Toulouse. When it comes to the Tripartite selection the National Olympic Committees will submit their requests to the Tripartite Commission. In reality, only countries with a max of eight athletes in the last two Olympics in individual sports, can be proposed. Later this Commission will select one male and one female going to Tokyo 2020. As it stands, I can not find any male or female that can be selected as the tripartite selection? One could speculate that if one of the best athletes could not qualify due to an injury, that person could be the selection. At the same time, the max country quota is two and further more that such selections often goes to athletes from smaller countries not so well represented at the Olympics.
