It's the new feature that should perhaps not have a key.  At
least it should not grab an existing key.  There are plenty of
unbound keys in Dired.  And why not just provide the command,
for now, and let users bind it themselves if they like?

So what?  Introduce the new as optional behavior.  Let users
decide.  What's the hurry to replace?

You changed the default behavior immediately.  That's a far
cry from providing, say, an ELPA package with the new feature
and letting users adopt it by choice, and then, after a few
years, discussing and deciding whether to replace the existing
default behavior.  What's the hurry to replace?

When will Eli stop personalizing everything?

I don't claim ill will - never have.  I do see a difference
in approach from what has been the practice.

What's the imperative behind this key-binding replacement?
Why not just offer the new feature as a plus, not a
