The latest directive I've received is that we should not spend any more 
time or resources on adding ZGC support to the SA.

I personally agree with that. I think the benefits provided by the SA is 
dwarfed by the cost to maintain it, so we should phase it out.

You should be able to find the excluded tests by grepping for 'vm.gc != 
"Z"' among the SA tests.

cheers,
Per
