I think you and the parent are using different definitions of granularity. The parent meant that sizeof(t) could be 32 or 64 bits. I think you just meant that the smallest thing the pointer references is the address of a single byte.

Rust already has fat pointers though. A reference to a smaller byte value could be a pointer plus a bit-mask.
