I can imagine that in really high-volume use cases (such as the OP
apparently has) the number of client connections might be so large
that identification by timestamp isn't useful, and the source IP will
be obscured after the first hop through a connection pooler or other
middleware. If you've got 100 connections per second coming in,
matching things up by timestamp across different machines is going to
be tough.
But I agree with your other concerns. I think the problem is real,
but I'm not sure that this is the best solution. On the other hand,
I'm also not entirely sure I understand the proposal yet.
