As a practical matter, I've never heard of (much less seen) a buffer that had to be replaced because of this level of wear.
I would guess that this is because the wear is limited to only a thin layer of the buffer as eventually that "cutting surface" on the edge of the retaining pin channel no longer contacts the buffer, as the buffer is pushed off by the rest off the bolt carrier that remains in contact with a larger portion of the buffer and the "cutting edge" can no longer dig further into the buffer.
