Unfortunately, one major attack vector is someone isolating your
node, getting you to sign away your whole wallet to fee, and then
selling it to a mining pool to mine it before you can figure why
your transactions aren't making it to the network. In such an
attack, the relay rules aren't relevant, and if the attacker can DoS
you for 24 hours, it doesn't take a ton of mining power to make the
attack extremely likely to succeed.

Not a fix, but would reduce the financial risk, if nodes were
not relaying excessive fee transactions.
