If it were me, I'd include both. Maybe the image is incomplete or vice
versa. The debug tree output is also human readable. I'd also put them
up in a cloud location where you can kinda forget about them for a
while, I've had images not looked at for 6+ months by a dev.

I would try to summarize something like:
file system created with btrfs-progs version -----, and mostly used
with kernel version -----, and inexplicably the file system became
unusable at boot time always mounting only readonly. Newer kernel
versions still could not mount it, nor was btrfs check using
btrfs-progs version ----- able to repair. See thread URL for more
details.

btrfs-image URL
btrfs-debug-tree URL

Yeah pretty much that's right. There is an rpm command where you can
have it check the signatures of all installed binaries, but I forget
what it is offhand. That'd be an alternative to reinstalling if the
init options were to work.
