You can look at the history of music and see a cycle of innovation and complexity. When people are focused on innovation - whether that be in technology, genre, or theory - the the ensembles get smaller and the orchestrations get simpler. People need to hear new things in a simplified way to grasp on to it and develop an ear for it. Once people are familiar with the new things, they desire greater complexity so the ensembles get bigger and textures get richer, with full classical orchestration being a maximally complex format. Then some innovation occurs, and things get stripped down again, rinse, repeat. When you hear about artists who were "ahead of their time," they were usually just a little off of this cycle in one way or another - either making new things too complex too quickly for people to catch on to, or making some fundamental innovation when people weren't interested in it.
All that to say, I'm not surprised people desire bigger textures and rich orchestration right now, because the last 30 years has been all about innovation in technology and genre, stripped-down textures, and simplification. It's well about time for people to start focusing on building all these new things up into more complex and challenging forms.
Many years ago, I listened to a radio interview, with people from the recording industry speaking about cycles in popular music. They said that we go through periods when there are many very creative artists around who are writing new kinds of songs and setting new trends. When these trends "set in" there are many other artists that copy the styles and its a bit of an upswing for the industry, but they reach a period of stagnation. They mentioned that during these periods of stagnation, music listeners look for other things and tend to gravitate more toward dance music, with that becoming more popular. People always need something to dance to. The industry then needs some fresh innovators to create the new wave of pop music that will capture people's interest. I guess this made sense to me. One thing I took from it is that music industry folks recognize cycles and they have some ideas of what causes them and what it takes to break them. I'm not sure how much of this still applies, but it is what I heard.
