Except that if you read the majority opinion they actually open up any provision of the law to challenge on the same grounds. They warn that the ruling should not be taken as covering anything covered by insurance, but presumably any such thing could in principle be challenged on the same basis, and depending on the circumstances might likewise be exempted. The majority has opened the door to challenging the application of any provision of this law to a closely held corporation -- indeed any provision of any law. They just don't know how the challenge will turn out.
It's interesting to note that the court broke down almost exactly on religious lines when dealing with contraception. Five of the six Roman Catholic justices voted with the majority, and all three Jews joined by one dissenting Catholic. I think this is significant because the majority opinion, written exclusively by Catholics, seems to treat concerns over contraception as sui generis; and the possibility of objections to the law based on issues important to other religious groups to be remote.
Another big deal in the majority opinion is that it takes another step towards raising for-profit corporations to the same status as natural persons. The quibbling involved is astonishing:
....no conceivable definition of 'person' includes natural persons and non-profit corporations, but not for-profit corporations.
Which may be true, but it's irrelevant. The question is whether compelling a for-profit corporation to do something impacts the religious liberties of natural persons in exactly the same way as compelling a church to do that same thing. If there is any difference whatsoever, then then the regulations imposed on the church *must* be less restrictive than the regulations imposed on a business. Logically, this is equivalent to saying the regulations imposed on a business *may* be more restrictive than the regulations imposed on a church.
