Triggering a resend on a re-order is reasonably sane, sending an RST isn't....

You get the RESETs from people that do anycast when your broken ECMP hashing splits the packets between multiple upstream providers. This might cause parts of your TCP stream to end up at entirely different destinations. Probably not going to happen with LACP but these things are related and often use the same knops in the configuration.
