Should routers send redirects by default?

I think the question is what sensible defaults should be. In my
environment we turn off proxy-arp and redirects, and it is my firm belief
that this is actually what should be the default.
In my opinion:
A host SHOULD support listening to redirects and MUST have a knob to turn
off this listening if implemented. A router MUST have redirects off as
default but MUST support a knob turning them on and when sending a
redirect it MUST forward the packet that generated the redirect.
I know most of the above is completely against current standards, but for
me these are more in tune with todays reality in networking as I see them.
