FWICT: Streamlined NTRU Prime (sntrup) has no known patent issues. Should be fine. Regardless, a "double-wrapped bitcoin address of some kind" can be specified, coded up and the relevant module replaced whenever the dust settles. I know Bitcoin doesn't (yet) have fee "weights", but i still think these addresses should be called "heavier" if they are at al significantly slower to validate.
