You don't need to, I wouldn't recommend it. This is what I would do:
1) Use choidujournx to downgrade/upgrade to whatever firmware you're aiming for while retaining autorcm (to avoid any fuse shenanigans)
2) Reboot your device into rcm and boot hekate
3) (Assuming you want a clean boot0/1) Toggle autorcm off
4) Dump your new clean boot0/1
Assuming the backup was made from an undetectable entrypoint like hekate or some other bootloader, and that there were no homebrew error logs then probably.
You're better off consulting this thread for ban-advice/warnings, I just knew how to get boot0/1.

(Just checked one of the tabs in the OP, they basically say what I said. As long as it's a nand backup prior to any tampering you should be fine in theory.)
Great advice. Bookmarking this one.
But to be clear, you need to upgrade/downgrade to the firmware using choidujournx that matches your original nand backup to extract a clean, usable boot0/1 right?
Also isnt theres a way to extract the boot0/1 from a raw nand backup?

You would only be updating with choidujournx to re-install the boot0/1 you need so you can dump it properly and then restore your nand.
Doing this will not affect your ability to update normally after restoring.
Since it sounds like you want to go completely stock, then no. Avoiding burning fuses isn't worth it in your case. (You might miss out on future warmboot exploits, or coldboot if you're on 3.0.1 or below)
Though I would still recommend keeping auto-rcm on until the point where you toggle it off to dump your clean boot0/1 and restore.
Just to spare the need of a jig if one isn't on-hand.

That's right, just keep in mind when backing up the target boot0/1 if you have autorcm enabled or not. As that is where it's installed.
Assuming package1 is included in the Nand backup then probably. Though I haven't personally tried or heard of anyone else trying, so continue at your own peril with that.
Edit: Just checked this page, seems like it's stored in some of the firmware titles.

Well, from what I've heard from my parents, he had a seizure last night, perhaps an epileptic episode, fucking died, had a near death experience, my dad called the paramedics, they showed up, took him to the hospital, and he woke up covered in tubes, and started complaining.
