No CSR/CCC for addition of "since=9" info to deprecated type of protected API's under javax.lang.model.*

As part JCK AutoSig activity, I am checking the difference between sequential JDK 10 build API signatures from which I noticed that
constructors of many protected APIs under javax.lang.model.* package were changed to add “since =9” to the Deprecated type of the corresponding constructors.
 
Change set in JDK10 build 30: (see the comment [1] )

JBS issue responsible for the change which does not have a relevant CSR request: JDK-8172818

 The aforementioned changes do not have a CSR request filed in JCK10 .
 
As per the CCC charter I read,
(1) Every change to the specification of an exported interface, either
          external or private, requires a CCC request regardless of the size of
          the change.
 
I believe this applies to protected API members whose signature is changed.
