No, they are mandatory. The following are mandatory as well:
Always according to the draft. So not all is lost. The latter are described as "fastest minimum-width signed integer types"; this means that int_fast8_t can perfectly be a 64-bit integer.
I guess that the intention of the standard with making fixed-width types optional is to support machines with exotic bit widths that are not powers of two. ISTR that some Cray were among these.
