My understanding is that this is already following the new inheritance
model. There's already a GEN11_FEATURES and it doesn't include an
ICL_11_PLATFORM because it doesn't need to (and CNL also doesn't have a
CNL_PLATFORM). What do you think needs to be changed?
The one thing I do see we lack is the __initconst keyword.
