I think the bigger issue is there are sometimes major features (like WSL and WSL2, especially) where there's no way other than joining Insiders to try out the features. In some sense it would be better if some of these kinds of features were in a separate beta somehow, or were not announced until closer to ship date. Instead, there are a ton of users who basically run beta versions of Windows 10 permanently on their primary workstations.
