The author talked about its effect on compile-times and I have to say, I agree with him. It's also why I dislike header-only libraries, they also bloat the compile times unnecessarily.

Don't get me wrong, the fmt library is very nice, but you can't deny its effect on compile times.

fmt/core.h has been heavily optimized for build speed and is usually faster to compile than equivalent iostream code: https://github.com/fmtlib/fmt?tab=readme-ov-file#compile-tim.... Once modularized std is available we might be able to be compete with printf.
