Why do we need a redirect path?

[loevgaard]

Right now it's possible to have a redirection path like A => B => C => D. Why is that?

Given this redirection path, if I add a new redirect that redirects D => E, then it would make more sense to update the redirects, such that:

• A => E
• B => E
• C => E
• D => E

This way we know that when we have a redirect it always contains it's final destination in the destination field.

UPDATED
Comment from @Roshyo: This would only be correct if all the redirects are permanent redirects.
