I’m not following. Work has been put into the User Card so that “higher” (eg. “gold”) badges get display priority and the “more” link will bring up the others a member has received.
Much thought and effort has been put into reducing distraction from the topic read flow, (eg. no Signatures) so I can’t imagine where having a mess of Badges showing in posts would be a good thing.
Consider a member that has ~3 dozen badges, would you really want to see all of them every post?
That said, there are plugin-outlets available and a plugin that would do that could be put together.
