you "not supposed to" or "not authorized to"?

If you can maintain suitable cloud clearance and maintain suitable
visibility, you can descend prior to VDP legally. This practice is frowned
upon since descending before VDP puts you into unprotected airspace. You may
have visibility which is sufficient to keep the runway in sight, but you may
not see the antenna farm that the approach was designed to keep you over.
