 ``N==__ARM_FEATURE_SVE_BITS``, the implementation defined feature macro that is
 enabled under the ``-msve-vector-bits`` flag.
 
-NOTE: This feature is currently WIP, the ``-msve-vector-bits=`` flag defines
-the ``__ARM_FEATURE_SVE_BITS_EXPERIMENTAL`` macro. This feature is complete
-when experimental is dropped.
