Notes: The old feature IDs were problematic because they attempted to follow specification section IDs, but some specifications weren’t aren’t always covered by a single section, and many sections were inconsistently named. Because there was no pattern one could predict for any of the headings, a new system was created; to name the feature and provide context. This meant a feature ID like css-cascade-all-shorthand became all-property, and css-fonts-propdef-font-variant became font-variant-property, etc. This greatly simplified all of the feature IDs and allowed for more predictive naming moving forward.
