I'm for it. Mostly because I'm getting old.
But I'm not sure everyone would be. Isn't the whole idea of the all-night-dance party a fundamental part of the "rave philosophy" or whatever's left of it? Redefining time frames, breaking out of the rigid schedule we are held to during the week... Being up and energized at 4:00am set us apart from everyone else, it made us unique. However self-centered it might sound, it was
our time.
All-nighters also show a certain devotion partiers have to the scene. It was an event to look forward to, to prepare for in advance -- not an object of convenience.
It seems a lot of us have forgotten why we started partying in the first place.
If all parties switched to daytime, a big part of it will be lost. It wouldn't be a rave. But it's a sign of the times and as of now, it seems like a good option.
