The Bitcoin API is fundamentally broken - it assumes that the daemon (that syncs up to the network) and the wallet are the same thing.
A) Please demonstrate
B) If A can be done, Please explain why it is a problem
Otherwise it is just FUD
Hrrrrrmm. My point is clear and obvious: https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_Calls_list - a daemon that syncs up to a p2p network should have no concept of "balance",and should thus not be able to "getbalance". Seriously, this is not FUD, and the fact that you don't know that the Bitcoin core team is working on this as a matter of importance is quite shocking. Have you seriously never used any of Bitcoin Core's RPC calls? These are extremely basic concept we're discussing here.
I run the daemon - I don't need to use getbalance but for people who mine with it (when that was still possible) it had value. You could easily see what had been mined. And that's a problem because...
How exactly does the ability of a daemon to check a balance hurt the platform?
Don't use that feature if you never have a balance for it to check. I don't, and it doesn't bother me.
