I definitely hope they generally move more design space to the subclass. It would increase page count, but it would make it easier to expand options. "Pick a feature" options like invocations are also generally good.
IE: if rangers had more room in the subclass (and no casting in the core), they could do a lot more with animal companions or specialist rangers. Monks could really open up to a lot more fictional archetypes, fighters could learn differnt kinds of magic, etc.
But I would not want to see subclasses go away entirely. Being relatively easy to get into (at least, for a game with this much crunch and variety) is a major benefit of 5e. Subclasses make it simple to figure out what the most important choices are for making the character you want. I wouldn't like it if that was removed.
If I'm understanding you correctly, I kind of agree with this. To be honest I think this is something that could have been handled much better in 5e. They weren't bold enough in committing to cleaning up the base class options by reducing the # and backing out features to give more design space to subclasses, and they simultaneously want to control the number of classes and pigeonhole all new concepts as subclasses into existing classes even when it's a significant thematic stretch to do so (i.e. psion or shaman.) So we're left underexploring a lot of those class concepts and getting a lot of unclean bloat in subclass options that don't leave a ton of customization room and can't be MC'd effectively.
I arguably think that 3e's prestige classes worked better as a concept, but that they needed to do the same approach and pare back or simplify what was offered through base classes.
