If fboundp returns non-nil, it means the symbol's function cell is not
void, i.e. the symbol can be used as a function.  Right?  So the call
can only fail if the function itself has a bug, right?  And in the
latter case, how is that different from any other Lisp function called
during loadup?

I think it's the same.  IOW, any problem that could happen at loadup
time could also happen during a regular session, and will have the
same results.
