Answer
Before Ivy, Angular needed entryComponents to know which components could be created dynamically.
Ivy removed this requirement.
Ivy removed this requirement.
Quick Answer
In pre-Ivy Angular (ViewEngine), entryComponents listed components created dynamically (not via selector in templates) so the compiler would include them in the bundle. Components referenced only in template selectors were automatically included. Ivy made entryComponents obsolete - it uses a different compilation model that discovers all components. In Angular 9+, entryComponents is a no-op.
