If some (or all) options strikes get suddenly changed and made "Non Standard (NS)", then only current holders can trade it anymore... And for the current holders it means there is no Bid/Ask by the MarketMaker anymore, b/c the MM stops providing liquidity for such NS options anymore! Ie. the current holders are lost! And this gets very much systematically abused recently, mostly with ETF options, but recently also with options of PACW --> BANC. These gangsters simply make a stock split and by this then declare the options as Non Standard (NS)... IMO clearly a "Systemic Systematic System Error"...
Non Standard options are there to protect holders from adverse price move due to corporate actions that knock the forward out-of-whack. They are definitely not used to screw holders over.
