Was it ever considered that the feature itself could be problematic,
security-wise?

I see at least two candidates:
- It's IMO generally a bad idea to distribute "better/newer" keys
over
a potentially already weaker trust path (i.e. something secured by the
old key).
- If some key was compromised (and thus the server itself) an attacker
might use the feature to distribute his own keys, which, during clean
up from the attack, might be overseen.
