Instead, parameters evaluate to QgsFeatureSource, which are used for retrieving features, feature count, crs, wkb type, etc. This abstracts away the actual feature source, so that algorithms may potentially operate from non-layer feature sources. It also helps remove the need for specialised QgsProcessingUtils methods like getFeatures, featureCount, and createSpatialIndex. Instead the standard API methods using QgsFeatureSources can be used instead.
