are hardship distributions protected under 411(d)(6)?

[KJohnson]

I agree. 1.411(d)(4) Q&A 2-(B)(2)(x)

[Scuba 401]

WIth regard to Profit Sharing Plans and 401(k)'s, can a hardhsip provision be eliminated by amendment? The way I read the Regs they can, but I want to confirm before doing anything.
