We've been able to run all three combinations up until now; what changed?
And, if we can only run two out of three, is it really best to skip 64-bit? If anything I'd think we should skip the 32-bit tests...
No, MRs have only been tested on Gitlab with wow64 only. The testbot also runs the full test suite with 32bit only (though maybe with win32 prefix), and only relevant tests with wow64 / win64.
At some point the tesbot was broken so I made this, but I would prefer to have the tests running on Gitlab if possible.
If nothing else, dinput isn't the only test that's useless under WoW64. In particular ntoskrnl and setupapi also come to mind.
Sure, feel free to add more tests to the include list after, and if, this gets merged.
