After Jigsaw, many SA-JDI tests fail. While we can fix the problem, we have also discussed taking this as an opportunity to remove SA-JDI.
SA-JDI has very little (0?) usage among our customers.
Sustaining agrees that it has little value for them.
SA-JDI does have a number of tests that are useful for exercising SA, so removing SA-JDI will get us lower test coverage. But many of these tests are quarantined anyway.
