Multiple registrations on IClaimsTransformation should compose. For pete's sake, the signature for IClaimsTransformation is literally an async reduce function.

Describe the solution you'd like

A ReducerClaimsTransformer should be injected into AuthenticationService.Transform

public class ReducerClaimsTransformation : IClaimsTransformation
{
    public async Task<ClaimsPrincipal> TransformAsync(ClaimsPrincipal principal)
    {
        foreach (var transformation in _transformations)
        {
            principal = await transformation.TransformAsync(principal);
        }

        return principal;
    }
}
