"He can still come back anytime and announce a deal on any of his tickers. "
Yeah he could. But how can any deal be completed (also goes for a name/ticker symbol change) if he can't get this ticker SEC Current because, if not, FINRA won't process future "corporate actions".
These are done for a long time, he can't afford to keep them updated with his own money. Sorry, but srnw gvsi and wnft will be going defunct very soon.
