Depends on where this process is well-documented: if it is available on iFixit or somewhere super obvious but if I've got to go to xda or some Russian hacking forum, download a bunch of files strictly internal to the company and hope someone made a video about it, then it doesn't matter how "well-documented" it is.

Also it's basically the core of the highly-paid tech expert meme "not paid for turning the screw but to know which screw to turn".

If the issue is not easily troubleshootable and searchable then the keyword for it if the device doesn't reach stage X of boot will always be "bricked".
