This is funny, I come from a different angle and see almost the opposite of what you see (being overly caricatural on purpose):

- where you see the dropping of an old cynicism, I see a lot of capitalist cynicism: where spiritual masters would spend years in prayer and meditation before teaching for free and providing help to all, we now have "life coaches" who ask absurd prices to guide you, because they had a "breakthrough" after two months of psychotherapy

- where you see modern spirituality without the traditions of religion, I see the form of religion (groups organized around a particular dogma, with churches organized around trademarked psychotherapeutic methods) without spirituality

Spirituality and mysticism are all about metaphysics: we got physics to an absolutely awe inspiring level of sophistication, but we still pretty much ignore completely what consciousness is (and we might forever). Spirituality is, according to me, entering into that mystery and poking at it. I personally think metaphysics is an essential part of meaning making, and as such of well being. But this means that I need to be able to discuss it with someone who cares about it, not someone who just sees it as a story that helps holding it together.
