I'm just glad the number-space has been sorted out. It was annoying to learn that ".NET 2", ".NET Standard 2" and ".NET Core 2" are very different things.
It's really too bad the naming/versioning has gotten so confused. I used to be a heavy .Net user, then stepped away for a while when I changed jobs. Every time I try and come back, I get so confused. Am I looking at the right docs? Is this API available for the platform I'm on? It's bad enough with .Net, itself, but what about GUI libs? What's even supported anymore? What's actually stable and not in pre-release? It's a shame, because .Net is damn good, but the messaging around it has been awful in my experience.
Old .NET was always ".NET Framework". Microsoft had many years of branding advice early in .NET history that it was never to be called just .NET because their branding teams were using that as a wider initiative that included other things. Most of those other things died or were rebranded and .NET Framework was the last one standing. .NET 5 was the first ever "just .NET", technically from a historical perspective.
