NAK. All this dancing around the infrastructure just makes changing
the infrastructure later be awkward and produce weird errors.
If something in the fixture failed, with this code you never enter the
subtest, making the test result 'notrun' instead of the correct 'skip'
or 'fail'.
What is the problem this is trying to solve? Incorrect engine list
used? If you have a subtest per static engine, all CI does is execute
per static engine. Converting this test to use dynamic subtests for
engines is the way forward.
