This is a kernel driver, and yes, kernel updates are independent of distribution development, although distributions are typically built around certain kernel branches. Debian (stable) is relatively conservative, and doesn’t offer the latest, cutting edge kernel, but will eventually include a kernel with this driver available.
This probably won’t have much impact for most use cases, though.
Not only that, but the effects are really only going to be noticeable on very large partitions/devices, like terabyte+ size. The typical thumb drive scenario will see no recognizable improvement in load speed. It’s still a nice improvement, don’t get me wrong, but it’s not a change that translates to any real-world improvement for most user cases.
