IMPORTANT: I am able to restore halt old behavior if I do:

apt install sysvinit-core 

Plus: Old RedHat based versions are able to power off with halt too.

I am trying to understand why in Debian 9 you should not use halt to turn off your computer anymore. That behavior are removed from systemd. I am a bit scary, but I think there must be a good logical reason.

Are other unixes or unix-like with this same behavior or are Linux turning into something different?

Now if you want to turn off the machine after the system shutdown you should use poweroff instead of halt...

Somebody know how this command are interpreted in other Unix-Like?

That is not a duplicated, because, debian 7 can power off with halt for example.
