AccessbileObject setAccessible array version vs non-array version

Hi all,
motivated by the recent "Java 9 build 148 causes trouble in Apache
Lucene/Solr/Elasticsearch" thead, I thought I ask... there is
AcccessibleObject#setAccessible(boolean), which will ask the
SecurityManager for permissions and then make itself accessible
according to the boolean flag. the array version takes an array of
AccessibleObjects, asks the security manager *once* and then makes all
of them accessible. So if you are in need to make a lot of objects
accessible the array version is superior in performance.
Now with jigsaw it is no longer a all or nothing for the class, now
single methods or fields may no longer be made accessible, even without
security manager. That means that even without a security manager set
using the array version on File for example will fail with an exception
(unless the module is opened from the command line, but we should leave
that out for now)
My question now basically is the following... why is this method not
made deprecated? It is kind of useless now, even misleading I would say.
bye Jochen
