It is actually not possible.
It's actually not possible.
All system apps has been installed on /SYSTEM partition by the phone manufacturer. This partition is in read-only and only the manufacturer has the right to write things on.
System apps also use another partition : the /DATA partition (also called user space). All the settings updates related data, users data and cache data are stored on this partition. It basically store all the modifications you could have done on the phone. All the apps you install are fully stored in there.
FYI, Performing factory reset from recovery is simply doing a wipe /DATA and a wipe /cache.

Without the right to mount /SYSTEM partition as read-write, it is thus impossible to delete system package from the phone. The only thing you can do is delete their cache and all the related user data. In the end, this method doesn't save any space on your phone.
**Note** : Factory reset will restored all the debloated packages !

Yes in the sense that you won't encounter bootloop. However you need to be careful on the google debloat list. I am not Google fan at all so a lot of google package will be debloat by default. You need to check what you want to keep in *debloat_lists.sh*

There is also a *Advanced debloat* section in my debloat lists which contains packages with useful features but can be removed without breaking (to much) the system.

You can for instance freeze the Play Store and the Google Play Services if you want. It's what I did on several phones and besides significantly improving battery life, it's not causing to much trouble if you mostly use apps from the F-Droid store.
If you plan to replace stock apps (Gallery, Videos etc...) by other apps, I'd like to propose the install of FOSS replacement in my script, stay tuned**
