I have made similar experiences like you when I contacted upstream and asked
for more information about previous CVE. I agree with you that their policy
makes future security support for us nearly impossible. Currently the main
purpose of libspring-java is to build other software from source. We don't ship
any application or web project that depends on Spring and exposes users to the
currently unfixed CVE which means the current status of all CVE in
Stretch/Buster/Bullseye (no-dsa/minor) is correct. It is also very unlikely
that Java developers who use Spring/Spring Boot for their web applications
depend on one of our Debian packages. 

In my opinion it is OK to ignore the currently known CVE. I would support
adding libspring-java to the list of unsupported packages because of the lack
of upstream support. We, as the Java team, should make this clear by mentioning
libspring-java in the next release notes for Debian 12.
