I'm not adding GUI elements to hand hold if that's what you're referring to. The opt-out is simple enough to use: send coins back to yourself until you're sure you have correctly tainted, regardless of the tainting method.
While certainly better than nothing, this also means somebody could just keep replaying and slowly bleed you out via miner fees. Worst case scenario, the chains get jammed up due to this. (Not Armory's fault, obviously.)
What I could do, since 2x insists upon the lack of 2 way replay protection, could be to detect the fork by its fork point and issue a message box warning whenever someone is trying to spend a UTXO that predates the fork point. However, not knowing if 2x has wipeout protection, detection may get a whole lot harder than just hardcoding a header hash and checking against it.
My instinct is to go with whatever will let users know that there could be turbulence, with the option for users to turn off the warning. Crappy, I know, but I have a bad feeling this fork is going to be jammed through with very little external testing, if any. Also, I believe it was Bitpay who surreptitiously tried to get miners to use btc1 when upgrading to handle SegWit. Who knows what other tricks signatories will use to get people to install some frankennode. When (not if) these come knocking and asking for help, it'd be good to have a plan.
As for wipeout protection, I seriously doubt that it does. The few PRs I've looked at gave me the impression that they're trying to do the bare minimum to meet their dumb agreement.
