Is NonNullType still necessary when nullable reference types is enabled?

[gojanpaolo]

Session # 2 demonstrates how HC leverages C#'s nullable reference types.
In Session # 6 NonNullType is used...

.ResolveWith<TrackResolvers>(t => t.GetSessionsAsync(default!, default!, default))
.UsePaging<NonNullType<SessionType>>()

...but it looks like it doesn't affect the generated schema at all.

The graphql type nullability is controlled by nullable reference types:

• Task<IEnumerable<Session>> GetSessionsAsync for non-nullable Session
• Task<IEnumerable<Session?>> GetSessionsAsync for nullable Sessions

Is it ok to remove the use of NonNullType if nullable reference types is enabled?
