Progress bars and meters are semantically very different even if visually they look very similar. If you have used 30% of your storage space you aren't 30% done filling your storage. (Well kinda, but you probably delete things occasionally and it isn't quite right.) Or if your GPU is at its maximum operating temperature and thermal throttling it isn't 100% done heating up. Basically many meters don't really represent progress. Maybe it could have been one element with `type=progress` or `type=scale` or similar. But at least for screen readers I can imagine that they would want to differentiate them. I imagine that the default styling may also be different, for a progress bar you may want some sort of throbbing effect to show that something is working while for a meter that typically wouldn't make sense.
