Why is Mediawiki programmed like this?

Page A ---OK MOVE---> Page B (history-less redirect to page A) but Page A ---BADMOVE---> Page B (history-less redirect to page C)

If it was:

Page A ---OK MOVE---> Page B (history-less redirect to page A) Page A ---OK MOVE---> Page B (history-less redirect to page C)

Normal users would be able to clean up page-move vandals who:

Page A --MOVE--> Page B Edit Page A

And effectively demand that an admin to the fixing. If the second set of rules was implemented, then a user who wanted to revert this could:

Edited Page A --MOVE--> Page C Page B --MOVE--> Page A Speedy Page C or leave it there if it's in a user namespace.

I'm telling you, one of these days a vandal is going to realize that Page moves require little work to be done but can cause massive damage that requires lots of work to fix, and then create multiple puppet accounts and capitilize on this behavior.

The only possible drawback that I can see with the second set of behaviors is that it means pages are a bit jumpier: you can put them on totally unrelated redirects, and you might lose some redirects in the process. But hey, they're redirects.
