That would have been the easiest/best solution here. However...haven't they uncovered a limitation in the filesystem here? The superblock data WAS fine, only the checksum was at fault. They found a away around the issue, wrote up their findings, suspicion about the flushing after a resize, and asked for more tooling support. This is classically a good blog post.

Oh certainly, but it’s not required of anyone self hosting who has a backup (and you need backups when someone else shots for you anyway)
