This is per the discussion in the CSR:

Thank you for implementing this change so quickly. Per the discussion in
the CSR, I have updated JEP 12 to allow suppression in the case above
(see http://openjdk.java.net/jeps/12#Relationship-to-Java-SE-APIs /
second list / fourth bullet) and also the JLS RFE (JDK-8231433).
The interesting takeaway is that use of a preview language feature
generates a non-suppressible warning (scan JEP 12 for "This message
cannot be turned off") while use of an essential API element associated
with a preview language feature generates a suppressible warning.
