This is true for leaf networks where hosts share links with routers.
This is useless in the core of the Internet where you only have
point to point links.
The vendor has no way of knowing if a GE or 10GE link will be used between
routers or between routers and hosts.
I've not yet heard of a single example of a router which does not support
Ethernet and in consequence would not need to implement Redirect for the
abovementioned reason.
So, back to:
1) should implement redirect
2) should NOT enable by default
right?
No, this is exactly NOT not what I'm saying. Instead:
1) must implement redirect
I was only responding to point 1), and I have no firm stance on 2).
However I must say that most reasons I've seen for disabling it have
been rather weak. For example this and the quoted message sum up a
'security argument':

I'll certainly agree that vendors should expose the default value in
configuration, no matter what.
