Time-in-the-future transactions are non-standard (as of 0.8?  I can never remember when things happened...) @p{par}

Why: because there is a fill-up-memory denial of service attack, and it really isn't reasonable to expect the entire network to store your timelocked transactions "forever". @p{par}

Even in the past, the statement "unspendable by the sender because of replacement not being implemented" was not true.  Wait long enough and only a subset of the network will have the timelocked transaction (because new nodes, old nodes restarting, etc). Broadcast a double-spending version without a timelock and it will get mined fairly soon. @p{brk}
