According to the Supreme Court ruling, "the Aadhaar number must still be quoted to file income tax returns and apply for a personal account number (PAN)."[1]
I don't have a aadhar card yet and I don't intend to get one. I have a pan card but I had it made a few years ago. I am not aware if things have changed, I'll ask around tomorrow for ground information.
Avoid getting it for as long as you can hold out. If you’re not reliant on government subsidies, the only coercion now is to link it with PAN and also quote it in the tax returns.
If you can afford the penalty for late filing of tax returns, go for that. There are still several review petitions against last year’s verdict on Aadhaar. The Supreme Court, as usual, is delaying hearing those. Check out no2uid on Twitter, rethinkaadhaar.in and others.

This is just one source but there's lot of others reporting the same thing. Do you have a citation that says otherwise?
