I guess I don't write enough rust to say this with confidence, but isn't that the bare minimum? I find it difficult to believe the rust community would accept using a library where the API requires unsafe.

Not at all. Some things are fundamentally unsafe. mmap is inherently unsafe, but that doesn’t mean a library for it shouldn’t exist.
If you’re thinking of higher level libraries, involving http, html, more typical file operations, etc, what you’re saying may generally be true. But if you’re dealing with Direct Memory Access, MCU peripherals, device drivers, etc, some or all of those libraries have two options: accept unsafe in the public interface, or simply don’t exist.
(I guess there’s a third option: lie about the unsafety and mark things as safe when they fundamentally, inherently are not and cannot be safe)

I have some experience and yes, unless you're putting out a library for specifically low-level behavior like manual memory management or FFI. Trivia about the unsafe fn keyword missed the point of my comment entirely.
