In corporate culture, anytime anything is labeled "Classic", that's code for "on the back burner until eventual replacement". Why else would Lightroom become Lightroom Classic, the connotation being "this is your grandfather's software that will be phased out...get on board with the future"? If this is not the plan, why would Adobe not continue calling Lightroom "Lightroom" and call the new one something else, even "Lightroom Cloud"? Four years ago, Adobe went subscription. Four years from now, they will probably go cloud-only. Keep your options open.
