Microsoft.AspNetCore.Http.Features for .NET 6 still in a preview mode

Is there an existing issue for this?

Is your feature request related to a problem? Please describe the problem.

I'd like to bring back the issue raised some time ago: #48266 since it is already closed and I'm not able to comment it.
Are there any plans to upgrade Microsoft.AspNetCore.Http.Features for .NET 6 (and higher)? Currently it is only in a preview mode, which indicates it shouldn't be used for stable solutions.
In the mentioned issue it's been said most of AspNetCore features has been moved to a shared framework. In my project I'm using IQueryCollection which seems to be not included there and the only option to have it is to still use Microsoft.AspNetCore.Http.Features.

Describe the solution you'd like

Updated and stable version of Microsoft.AspNetCore.Http.Features

Additional context

The package was moved into the ASP.NET Core shared framework and isn't shipped separately to NuGet anymore (which is why it appears to be out-of-date).

If you use a framework reference you can build against the types with a stable version of ASP.NET Core.

For example, this code successfully compiles a console application which references types from Microsoft.AspNetCore.Http:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
  <ItemGroup>
    <FrameworkReference Include="Microsoft.AspNetCore.App" />
  </ItemGroup>
</Project>

using Microsoft.AspNetCore.Http;

var context = new DefaultHttpContext();
IQueryCollection query = context.Request.Query;

Console.WriteLine($"The type of query is {query.GetType()}.");

Which outputs:

The type of query is Microsoft.AspNetCore.Http.QueryCollection.
