Configuring innodb file per table was pretty common years ago when I last worked with MySQL. I thought the entire file gets deleted if you nuke the table. This would be for the default config with a single innodb file right? To remove some tombstones.

Yeah this tool was written to help recover from accidentally `rm -rf` the entire mysql data folder. The `page_extractor` you can feed it the whole block device and extract all InnoDB pages that has checksum that match.
