Scaffold context efcore does not generate .HasIndex statements

Given any schema (here’s one below). When running efcore scaffold-context, all goes well but the HasIndex statements are missing. Why ? Also, if efcore does not have those .HasIndex() will run queries differently ?

Scaffold-DbContext "Server=$  YourServer;Database=ContosoUniversity1;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -Force   CREATE TABLE [Instructor] (     [ID] int NOT NULL IDENTITY,     [LastName] nvarchar(50) NOT NULL,     [FirstMidName] nvarchar(50) NOT NULL,     [HireDate] datetime2 NOT NULL,     CONSTRAINT [PK_Instructor] PRIMARY KEY ([ID]) );
