Tested on XPS 9345 as well, success. As I’ve mentioned in the bugreport its lacking some features compared to linux-next kernel, but installation was very smooth.
I have Bitlocker on, script also did not work. Failure point:
$ sudo dislocker -vv --readonly "/dev/$part" -- "$tmpdir/dislocker"
+ sudo dislocker -vv --readonly /dev/nvme0n1p3 -- /dislocker

Perhaps makes sense to add optional argument to pass decrypted partition directly? eg.
sudo qcom-firmware-extract --disk-c /dev/mapper/bitlk-0a5e85ff-b32b-438f-93b1-8583f5a48a35
