In truth, this bug was embarrassing and probably annoying, but no worse than garden variety SSD card failures. No 3rd party rescue software is needed if you prepare for the inevitable SSD failures from the start.
Mender isn't a "rescue" program, it's a solid tool for firmware distributors to be able to update devices and avoid this problem. Article is marketing material, but good advice.
