As primary control, definitely not manual. But you need to provide full manual as a backup options. Even in today's most advanced commercial airlines, there are multiple level of control laws in place. Normal law is basically pilot telling computer what to do, but the pilot better know what flying is when the system kicks all the way down to direct law with no protections at all.
Remote diagnostic and control is great until that ability is gone. You always need an onboard backup option in the event of a system failure unless death is an option.
