The just-released Lightroom Classic CC 8.3 version (announced in this thread) brings also this change . . .
With the release of updates today, Adobe has officially dropped “CC” from the name of their applications – giving us Lightroom Classic and Lightroom. Yes, that’s right, “Lightroom” now specifically refers to the cloud-based application, as well as to the entire cloud ecosystem. When distinguishing among cloud-based components, Adobe will now refer to Lightroom Desktop or Lightroom (Mac/Win), Lightroom Mobile (Lightroom iOS and Lightroom Android), and Lightroom Web.
