The original has lots of 255/63 partitions. Most of my filesystems use 1k blocks.
I seriously doubt that. And I don't think it's even possible because the normal kernel pagesize on x86 is 4KiB since forever, and the file system block size has to be a multiple of that which makes 4KiB the minimum fs block size on x86. For tools at least 5 years old, ext4, XFS, and Btrfs all default to 4KiB block sizes. Btrfs still uses a 4KiB block size but now uses a 16KiB node/leaf size by default for storing metadata and inline data.
