Unknown, so future, gen are marked as -1 which we want to treat as -1u
so that always pass >= gen checks.
Do we really want to enable the tests when platform is not fully
enabled in IGT?
What does "fully enabled" mean?

If the test is checking for just "gen > x", the test should work
already. If the test is also checking for "gen < y" then we get a
spurious failure, but either way CI is going to tell you that
something is not passing. Without this it will be a skip, along with
skipping in the case that should just work already without actual test
changes.
And for a very large fraction of tests, the behaviour of next gen
follows current gen. Those that do not are very interesting, and will be
a much smaller number than the volume of skips we have to process.
