I have a different take than many others. 5e is a good, fast running (and DM prepping) game. In order to make it even more accessible to new players, some of the subsystems that requires more future planning for character advancement are optional. Does the game play fine without them? Well, are lower levels it will, though the fighter loses out on his ability with more ASI to pick up cool non-combat options like Actor and gain additional non-combat abilities. Also, without feats all advancements become "just a math adjustment" which one friend of mine finds ultimately boring.
Feats give players more options. IMO, leaving them out constrains characters to only doing what their class and backgrounds say. I strongly encourage them, and may not join a game without feats. (That said, a DM limiting access or removing some of the combat-only feats wouldn't bother me as long as I knew it when making my character.)
Multiclassing is a slightly different story. The classes are all interesting and you can easily play them 1-20. And there are variations within each class for even more play. If you picture classes as coins scattered on a piece of paper, there are parts of the paper that still show through, and multiclassing helps there. IMO it's more important as players have multiple characters under heir belt and want to try something else, but it can be a useful tool to helping define a specific character. I think it's useful, but not mandatory.
