To me this is really simple: If many/most ISPs continue *not* adding
useless/artificial/synthesized PTRs, the content / server people will
have no choice - if they want their content to get out and their
services to be used by the large majority of IPv6 users, they'll have
to accept connections from IPv6 addresses without PTRs.

Speaking only for myself: We're not planning to add useless IPv6 PTRs.
