I don't know, honestly. But if it's just a matter of reducing bloat, you don't really need LTSC. For example, you can remove preinstalled apps on Home/Pro with a line in Powershell: https://www.tenforums.com/tutorials/4689-uninstall-apps-wind...

LTSC is cleaner out of the box and has much longer support, but otherwise it's not that different. And Edge on LTSC still does annoying things, such as adding a Bing search box on the desktop, for example.
