No, that's really not the case at all. The books encourage reflecting, fairly aggressively. Beyind what the PHB and DMG encourage, look at the Xanathar's Guide sections about each Class and teflavlring suggestions.Not to me. Not in 5e.
5e blends mechanics and flavors together. It is all baked in.
As a DM, I rely on narrative adjudication − meaning, flavor is more important than mechanics for determining the outcome of a scenario.
In 5e, I refuse to fight against the tide of flavor. Period.
I want a Psion class, whose mechanics and flavor are for the purpose of actualizing psionic themes.
