Various Questions About Installing Homebrew to a WII U

Today I wanted to play Wind Waker on my Wii U when the game pad was having various issues with the joystick. I originally looked into buying a Pro Controller but I don't play on my Wii U enough to warrant spending money on a Pro Controller. I then wondered if I could use my switch Pro Controller which lead me to learning about Bloopair. That however would require me installing homebrew to my WII U though which lead to a few questions.
Q 1:

Does homebrew remove save data on the console? This has been my family's Wii U since the Wii U first came out so I wouldn't want to lose any of that save data.

Q 2:

If I mess this up have I caused irreparable harm? Similar concerns to question one, I don't want to cause irreparable harm to a console that has been in my family for about 12 years.

Q 3:

What are some good tutorials to follow? I'd want to make sure I'm doing this correctly.

Q 4:

There are multiple loader things, which is the best one? I did a bit of research and learned about Aroma and Tiramisu, Which one is better to use? If I did this what should I install?

Q 5:

Once doing the install, is there a way to add more plugins post jailbreak? The tutorial I watched had it install various plugins before the process of getting it on the Wii U and I wanted to know if I would be able to install any I figure out I want after doing the exploit.

Q 6:

Should I do it? Are there any drawbacks or anything that would make it so I shouldn't do this? I've never jailbroken a console before but I do have a bit of tech knowledge from coding as a hobby.

Q 7:

How do mods work? Would I be able to play mods of games with the homebrew?

Q 8:

Would I be able to play any games I don't own? Would I be able to use Roms of games rather than the physical copies or would I still need to insert the disk

Q 9:

How does this interact with the Wii functionality? Would I still be able to use it to play Wii games? My original Wii is effectively bricked since any disks put into it will be instantly spat back out (If anybody knows how to fix this that would also be helpful). If this lost Wii functionality I wouldn't have any way to play Wii games which would make me sad :(

Q 10:

Would this be reversible? If I decide I don't want to use the homebrew version of the Wii U would there be a way to use the Wii U normally?

Q 11:

On a scale of 1 to 10, how likely is it that Satoru Iwata would come back from the dead to haunt me for installing homebrew to the Wii U?

Q 12:
Is there anything else I should know? I'd like to be as informed as possible before making this decision.
