Yeah. Just checking if anything easy was on the table, because this patch is going to be backported to at least some LTSes. I tried to `patch --dry-run` the current diff, and this was the result:
 - JDK 25u: Applies cleanly
  - JDK 21u: Applies with minor conflicts in `src/jdk.compiler/share/data/symbols/symbols` and `test/langtools/tools/javac/sym/ElementStructureTest.java`
 - JDK 17u: All the hunks fail, because [JDK-8257733](https://bugs.openjdk.org/browse/JDK-8257733) moved stuff around
 - JDK 11u: Have not tried, I assume it is at least as bad as JDK 17u

So "superfluous" changes in `data/symbols` do not look like the practical problem, AFAICS.
