oneplus frustrations and the "my-" partitions

why in the fucking world did oppo split the system partition into ELEVEN WHOLE PARTITIONS full of random bloatware??

they're not symlink'd into /system, so they're unmodifiable by magisk modules. TWRP doesn't even detect them as valid mounts, and they're erofs formatted to prevent remounting. if you want to gawk at the full list, here you go. i've added what i (think) they're for in parenthesis next to the name.

/mnt/vendor/:

• my_product (contains base gms apps)
  
• my_engineering (fuck if i know)
  
• my_stock (contains oppo/oneplus/heytap apps, some of which aren't even used depending on region)
  
• my_region (carrier stuff)
  
• my_bigball (US/EUR app substitutes, i.e. google dialer, which replaces oppo dialtacts)
  
• my_manifest (no clue)
  
• my_heytap (probably oppo cloud related resources, this is empty for me because i'm american)
  
• my_preload (carrier and ad bloat)
  
• my_company (literally no idea, it's structured like a system partition but has nothing inside)
  
• my_carrier (more carrier configurations)
  
• oplusreserve (configs of some sort??)
  

WHAT THE ACTUAL FUCK??? why are there SO MANY??? some of these are quite literally empty and useless. others contain apps and data never even used somehow. none of this makes sense?? whoever's idea this was is an evildoer beyond human comprehension. i take this personally. (/j)
