To clarify, "full privilege access" (aka "full power") is not really a 
new concept.

Module access was introduced in Java SE 9.  A full privilege access 
(despite the name of `hasPrivateAccess`) necessarily includes module 
privilege.   Before JDK-8173978, a Lookup with private access always 
includes module privilege.  After JDK-8173978, the module privilege has 
become independent of private privilege and hence this new 
`hasFullPrivilegeAcess` method, a correctly named method, is proposed.
