----------------
I'm not sure we want to reuse the features:
- everything will get stuck with FeatureZCZeroingFPWorkaround, right? (but maybe we can remove features in this list?  I don't think so)
- it probably becomes harder to tune later chips, but that's admittedly a theoretical problem at this point
- some of the features can be generation-specific
