Any empty members in struct xpvcv AKA CV that an XSUB can use?

Id like to know if there is a 2nd unused memeber in struct xpvcv. I know 
that  union xcv_start_u  that has "OP *    xcv_start;" also has the very 
awesome "ANY    xcv_xsubany;" which is used by ParseXS and manually by 
me in CPAN code. "union xcv_root_u;" contains the xsub's C func pointer 
so that is occupied. What about     PADLIST *    xcv_padlist; as a 2nd 
ununused member for XSUBs in struct xpvcv? I'd rather not resort to 
magic to add a 2nd magic value to a CV * if I dont have to.
