I use a DAC at my desk too (the sound quality is that much better), but, like you said, I don't carry one with me. I always use wired headphones. Every. Single. Time. I detest the sound quality of wireless audio. When I'm on the road, on a plane, or away from my desk I *do* use the headphone jack. Yeah it's not the majority of the time, but I'd miss it a lot if it went away. I *assume* I could use a dongle, but that's one more port being occupied. Anyhow, my vote is leave it alone. It's not like the mic jack that saw little use.
