No I mean what real goal are you trying to achieve here that spam is making difficult - like presumably it's possible that we drop the pr entirely, but that doesn't actually do enough and there still ends up being "too much" spam. Or maybe the pr does go in and it turns even with it, there isn't a market for this nonsense and bitcoin doesn't end up with "very much" spam. What's the "business goal" that's affected by success or failure here, as far as you're concerned?

(For me the primary metric is "can a cheap node keep validating the blockchain", and to a lesser extent "is the long term tx fee rate level and its variability reasonable". I could probably put numbers on the first, though the layer is, at best, "i know it when i see it")

The first two of your metrics above have been met in the past month, I believe; is there some way in which bitcoin had been unusable for you in the past month?
