I wouldn't mind seeing E-nights come back too. But really, for my family, it isn't a big factor. My DW and DD7.5 just don't get up early enough for morning EMH. And I doubt given that we are next going 8/15-8/20 that there will be enough energy for an evening EMH.
The only EMH-related planning we did was to note that the Monday of our arrival that evening EMH for MK was removed. We were always planning on MK our first day, but the park will be open until 10pm anyways. We'll be "home" well before that. Tuesday we're doing Epcot when there is evening EMH at AK. Wednesday we're doing MGM since we have the Fantasmic package that night. We might even do a morning swim and head over to MGM closer to mid-day since we'll be there until the end of Fantasmic. Thursday we do MK again by choice since we moved AK to our Friday so that former neighbors of ours from MA (and one of my DD7.5's best friends) who now live in Stuart, FL can take their DD out of school for a day and come be with us at AK (their choice, which we were fine with).
Knowing that later arrival in the morning means less can be done has already been communicated to my DD7.5 ahead of time. We subsequently put together a list of 5-7 "can't miss" things at each park. We should be able to do that at each park. My only concern was Soarin and TT at Epcot, but if we get late day/evening FPs, we'll head out and come back later.

On a related EMH note, a friend of mine who is there now said that there were tons of people at rope drop the other day who were pissed off big time since they didn't know that EMH hours have been changed up. Oh well. Too bad for them.
