Ok. I guess you're presupposing that a new coin deletes the old irrespective of wider opinion? I agree that would be a problem.

The rationale for Devcoin was to 'give money to open source developers for their work in as fair a manner as possible'.

This purpose via associated generation/mechanics never lent itself to passive interests. This is now self-evident, even if it wasn't before. Whether that's due to any or all of distribution errors, naivety, greed, quality, concentration, oversupply etc is debateable.

But on your statement - why should you or I be 100% supported for doing basically nothing for X years beyond waiting and hoping? It particularly doesn't make sense to address apparent oversupply (I don't necessarily agree that's the core problem) by incorporating a supply swap.

That's the only aspect I'm referring to. However I don't actually know your opinion on new-coin, and you may be justifying interests in other changes for other reasons. As do I.
