I'd hope that we could find someway which would be both technically doable and tenable by most users, sooner rather than later.
There is no need to get it done soon because the account tree is still tiny should remain very small for years to come. I'm not even sure there will ever be a real need to implement it.
As of current price according to
http://crypto-prices.com/XCNSomeone who doesn't want the coin to grow up can send the minimum amount "0.00001 XCN" plus the fee "0.0000001 XCN" to 1 BILLION addresses to increase the tree size and that only costs him 5.81 $.
That's why it's needed and I'm sure you understand that as you "the developer" is the first who suggested it.
