Scaffolding with NRT generates non-nullable navigation property from principal to dependent

[roji]

Scaffolding the following schema in a project with NRT enabled:

CREATE TABLE Principal
(
    Id INT IDENTITY(1,1) NOT NULL PRIMARY KEY,
);

CREATE TABLE Dependent
(
    Id INT IDENTITY(1,1) NOT NULL PRIMARY KEY,
    PrincipalId INT NOT NULL,
    CONSTRAINT FK_A_B FOREIGN KEY (PrincipalId) REFERENCES [Principal](Id)
);

CREATE UNIQUE NONCLUSTERED INDEX [IX_Dependent_PrincipalId] ON [Dependent] ([PrincipalId] ASC);

... generates the following CLR type for Principal:

public partial class Principal
{
    public int Id { get; set; }

    public virtual Dependent Dependent { get; set; } = null!;
}

The Dependent navigation property should be nullable.

Yeah, I think it makes sense - will bring to the team for discussion.
