There are games that definitely subscribe to that line of thinking. I actually have a favorite system that lands somewhere between the two. Iron Kingdoms the war machine RPG had you choose two half classes at the start, and as you leveled up you had the opportunity to add more classes or dig deeper into the two you already have. It creates dozens of combinations of the core classes while still having a more pointed structure to keep you focused on what you're good at.
