Well, Gavin explained in #bitcoin-dev that the plan is actually to have two addresstypes, one for "vanilla" old-timer transactions, and another as catch-all for "advanced" OP_EVAL stuff, which is something I am quite fine with.

Now, the transaction type pluralism is mildly disturbing. People manage to terribly screw up (and whine) with just one transaction type exposed to them and supported on all client soft, I can only imagine the magnitude of chaos when there is a whole load of divergent transaction types with affinity to a particular type of wallet software.

Good thing BTC is not a corporation. We'd have to hire entire India and most of Ukraine for tech support
