It probably is still legal, but it’s not something I’ve looked for in like a decade. We do have products that use ground kernels, but those aren’t good to use on skin–the milling process doesn’t produce uniform particles and the pointy bits tend to compromise the barrier skin provides with very small tears.

I completely agree that plastic isn’t necessary for good soap, I just like it. I would definitely buy soap made with ecologically responsible plantstic at least once.
