I agree, things are not as bad as they seem.

I may be repeating the obvious here, but the 1.1 Age header will do
away with incorrectness due to unsynchronised clocks, at least in a
pure 1.1 chain.  Once everything is 1.1, unsynchronised clocks will no
longer threaten correctness.

They will still threaten efficiency though, due to some unfortunate
properties of the (current) HTTP/1.1 age calculation algorithm.
