Right, last implication is true from 8.3, and wrong before that, thanks for

FEAT_JSCVT implements the functionality identified by 0b0001.
In Armv8.0, Armv8.1, and Armv8.2, the only permitted value is 0b0000.
From Armv8.3, if Advanced SIMD or Floating-point is implemented, the only
permitted value is 0b0001.
From Armv8.3, if Advanced SIMD or Floating-point is not implemented, the only
permitted value is 0b0000.
