It seems like that at first glance, but this is going to dramatically increase the disk space needed by sites. On a small site, it may not matter much. But on sites with large media libraries, it’s going to be extremely problematic. In addition to needing more disk space, it will also make backups, restores, and migrations more challenging.

The developers have said that they’re asking for people to test things out to make sure it works, but these kinds of problems are going to surface after months or years — and they seem to be completely ignoring the ramifications of this.
