My issue was one that if the orig dev comes back, he may change something and make all your work go to crap....
Majority of hashpower and service providers like exchanges win, not developers.
Yeah, it's largely out of the original developer's hands, as the blockchain is "in the wild" now. Short of releasing a closed-source client with incompatible changes and somehow convincing the community as a whole that shunning the open source approach to cryptocurrencies is somehow better, there aren't any changes pocopoco can make that invalidate any of our own efforts to improve the coin.
Having said that, I doubt improving the client much was a high priority for pocopoco. Seriously, he didn't even take 30 seconds to grep the source for any remaining occurences of "NovaCoin" or "NVC" and correct them.
