"All this ruling did was strike down the “may issue” requirements for concealed carry in NY."

Presumably, if enforced by the Supreme Court over the next decade plus, it'll apply to NY's new "may issue" for simply owning a gun, as well that in NYC and Massachusetts. No "Shall Issue" law is relevant to bearing an arm if you can't even own any.

And to the other 6 slave states in the US: Hawaii and New Jersey which are No Issue at all, California as you noted, Maryland where at least in times past people who could demonstrate a real need got a permit for the duration of that, and Rhode Island which is a mess. And maybe territories like American Samoa.
