Instead we got one of the most epic fight scenes in the history of the MCU. Here's hoping that BRB shows up in AotG, they did have a nod to him in Ragnarok as a giant bust over the coliseum.
I guess their reasoning not to introduce new characters is that they would have felt out of place, the movies is already dense with characters. Imo it would have detracted from the emotional response they were going for.
Also on a side not, the kid that was grown up at the funereal, and was shown at the end of Iron Man 3 to be smart and technically adept could take over Stark industries and become the next Iron Man, I doubt it but it's a possibility.
