Typography systems are governed by structure, not preference. Font formats exist because operating systems, rendering engines, and historical constraints demand them. DFONT is a product of that reality. It was designed specifically for macOS environments and remains relevant wherever legacy Apple systems, archived design assets, or historical software stacks are involved. Treating DFONT as outdated ignores how long technical debt persists in real production and archival environments.

Font conversion into DFONT is not cosmetic. It is a structural operation that determines whether a font is accepted, indexed, and rendered by macOS. A visually similar output that fails system validation has zero practical value. This is why DFONT conversion requires dedicated tooling rather than generic, all-purpose converters.
