Yes, that's an omission - ACPI hasn't seen as much churn recently as
it did for a while, but the underlying problems with iasl's lack of
backwards/forwards compatibility has not been resolved.

Would you be happy to do so?

[Nhi] Yes, I would be willing to take a look at this as a different topic.  At this moment, it appears that only version 20200110 would work with our code,so we will need to state so specifically in our README.md.
