That'll only happen when Feige and Perlmutter don't have beef with one another. Plus, I think in Marvel's case, the greater universe has moved beyond things like SHIELD. With Ultron, the Guardians, Doctor Strange, and the Infinity Guantlet, SHIELD itself feels like a remnant of Phase 1 and some of Phase 2.
And the Defenders stuff probably wouldn't even be a blip on the Avengers' radar, especially when all that stuff, right now, is contained between Harlem and Hell's Kitchen. Not much the films need to acknowledge as far as the shows go right now. Especially when it's just Jeph Loeb who said the whole 'It's all connected' stuff when no one in the films said that. Heck, even the Civil War writers didn't know about the Inhumans stuff SHIELD had been doing.
