• Fundamentals > Logging: Although the purpose of remarking on "client-side" for several of the features was merely meant to mean from the original text/purpose that the feature also works client-side, the section heading use of "client-side" implies that it might not work server-side, when it actually does. Therefore, I'll probably be dropping "client-side" from headings where the feature/example works for both.
• Fundamentals > Routing: Router's NotFound content is never used in new Web project style aspnetcore#48983 pertains to the removal of the <NotFound> fragment. I need to run thru the docs and confirm that it's out for 8.0+.
• Components > Class libraries: Check for additional updates per ...
  • Create Blazor server-side rendering guidance for Blazor component library owners aspnetcore#47624
