[GoLightly]

He gave the power to bind and loosen ("the keys") to the original set of Apostles (minus Judas). "The keys" are not physical keys but the authority from God. The Apostles, in turn, passed that on to their successors, by the same authority.

He gave them to Peter, along with the charge to feed His sheep. Your position on it, that they were given to all of the Apostles & their successors is an interesting innovation.

[FormerLib]

He gave them to Peter...

No, He says he will give them to Peter and further describes them as having the ability to bind and loose in Heaven and on Earth. When this is given, it is given to all of the Apostles as a group.

Innovation? Hardly. You need to re-read that part again. Christ says "I will give you..." [that's future tense] and then He gives it to all two chapters later.

The reference to feeding the sheep has to do with +Peter's tripple betrayal, not about giving the keys.
