It would fit into the product matrix where Vista and Win7 Ultimate did: explicitly targeting enthusiasts, parts-builders and boutique shops where they want to convey that you're getting a cost-no-object build.

Or being able to sell it as an aftermarket license upgrade would be a way to get more revenue from people who were otherwise going to ride an OEM Home license for which MS had a negotiated rate of 34 cents per machine.

OTOH, one thing about the ongoing advertising/enshittification bubble is that it seems to distort people's understanding of revenue and NPV. They'd rather have the possibility of infinite future ad/spyware revenue even when people are clamoring to offer up-front real cash instead.
