No systemless/Magisk support.

Currently, installation of InviZible requires writing to /system, for some this can be seen as undesireable, because it may break dm-verity, and makes restoring device to stock longer as the entire /system partition must be rewritten, instead of just boot partition for the majority of Magisk installation in order to restore to stock.

Currently, a recently updated dnscrypt-proxy2 Magisk module is available: https://github.com/Magisk-Modules-Repo/dnscrypt-proxy2

Why do you think so? You are wrong! InviZible never writes anything to /system and can be used completely without root privileges. Read the project's wiki.

Everyone uses tools for their own purposes. The Magisk module is good, but InviZible can do march more things.

Ouch, ouch, sorry for assuming things. If I use the root installation, where does it write? It's own /data?

EDIT: Root is used to start binaries on own app /data as PID 0 https://github.com/Gedsh/InviZible/wiki/Run-Modules-With-Root-option.
Closing issue.

InviZible does not use root for an installation.

Yes.

Root is used to start binaries on own app /data as PID 0

This is just the option. Root is mainly required for modifying iptables rules to redirect internet traffic to InviZible modules.
