I think they've made it obvious at this point that every show prior to Disney+ won't be referenced or recognized. Edwin Jarvis was a nice appearance in Endgame but I also think that was just a nice "oh, Tony's dad had his own JARVIS too" and the stars aligned a bit there, what with Markus, McFeely and Feige all being involved with Agent Carter. Maybe there's plans for more Howard Stark appearances in the future and therefore more Jarvis.
I love Agents of Shield, but at this point I don't ever expect any film or television show to acknowledge it, nor do I expect to see any of those characters come back and reference their adventures on that show. I'd love to see Quake pop up somewhere on Disney+ the same way I'd love to see the cast of Daredevil come back. But it'll all be soft-reboots of those characters in my opinion.
