Why is move_iterator::operator-> deprecated in C++20?

As far as I know the reason it was removed.The expression (*i).m, where i is an iterator, and the expression i->m have the same semantics.Input iterators are required to support the -> operator, and move_iterator is an input iterator, so move_iterator’s arrow operator must satisfy that requirement.But I guess not like that.For a move_iterator, *i is an xvalue, so (*i).m is also an xvalue. i->m, however, is an lvalue.Consequently, (*i).m and i->m can produce observably different behaviors as subexpressions.Is this exactly why it is deprecated in C ++ 20 ? Are there any other concepts and disadvantages that should not be used ?whats the best practice about this ?
