I thank you for asking the advice of the community.
As our colleagues suggest, having 6to4 relays inside the network helps to reduce the latency. Opening up your generous services to a larger Internet community by advertising the 188.8.131.52/24 BGP prefix outside the network could have extreme and unintended consequences.
To give you an idea, a lot of the Internet in India depends on the service of the Tata companies, with international routing coming from Tata Communications AS 6453. Announcing 184.108.40.206/24 to 6453 as a customer, I would worry about its treatment as BGP best-path, in place of closer 6to4 relays. As you understand, these circuits are very far away, and also very full. This is not something I would recommend.
