Honestly, the best of both worlds would have been to have the simple kernel implementation and put the boilerplate recovery code in the system libraries. For instance, libc's write() should handle interruption resumption, and libc should also provide a write_interruptable() (okay, appropriately shortened for the symbol limits in early linkers) to expose the raw system call in the uncommon case that the programmer wants to manually handle interruptions.
