It would be, but the most realistic, specifc claim you could typically make is that some hypothetical feature that probably hasn't even been dreamed up yet would get done in less time than it normally would.

It's a hard sell, and that's precisely why it doesn't get done.

Maybe I'm misunderstanding. I think "the benefits [of technical debt]" are the reasons for taking on technical debt. When you take on technical debt it's for a specific feature that's needed, not for something that hasn't been dreamed up yet.
