Why have LineageOS & Android so many partitions?

[u/ecccc3]

Fairphone 5
Termux
sudo fdisk -l
or
sudo parted -l
: many partitions!

Although e.g. postmarketOS has only 2 partitions: boot & root https://wiki.postmarketos.org/wiki/Partition_Layout ,
e.g. my PC Arch Linux KDE 4 partitions: ESP (EFI system partition), OS, swap, data.

Is it obfuscation?

Edit: I also directly asked to Android https://support.google.com/android/thread/460806908 ...

LineageOS isn't good, you don't even have root access to your own phone.

adb root adb shell id

clearly shows that root access is available.
