The original proposal I started this thread with hasn't even received comments - presumably it's uncontroversial. The other discussions are about how to handle fees in requests that use the payment protocol, which isn't currently used anywhere so doing things differently isn't possible.

On the other hand you have been talking about a fundamental change to the behaviour of how all Bitcoin nodes operate, which is off topic for this thread.

If you have something specific to say about how floating fees should be managed by SPV wallets or how fees should be negotiated when the payment protocol is in use, this thread is appropriate. Otherwise please take it elsewhere.
