The hypothetical scenario being discussed is that you have already
replaced the former (good but now possibly suspect) public key with a
spurious new one. If that were to happen, you would be in danger of
accepting trojanned packages signed with this new fake key. My point is
that you would also *reject* packages signed with the new good key, and
this would be noticed very quickly (basically the next time you did an
update).
That is an extremely unlikely possibility as you have to generate a key
with the same key id (fingerprint)as the original.  Also, you have to
determine how to trick all users in to replacing the original.
All users? This is like spam email, you only need to succeed in a few
cases to get benefit. And distributing the fingerprint assumes you can
do that securely as well.
