 In short, it would add too much complexity to justify the potential benefits. It would unacceptably increase
 the maintenance burden, the testing requirements, and the benefits would be minimal.
 
 Concretely:

   extra logic would need to go into the pandas core codebase, which is already very complex and hard to maintain;
