In the true spirit of UNIX, it’s tar -h

It's tar --help on my system 💥

GNU switched to long command switches a while ago. Try bsdtar, it's still just -h.

They kept the short ones for the actual extract/compress commands though, for compatibility reasons I presume.

tar -?, -h is dereference or smth.

Nope, tar spec doesn't say anything about a help message. The man spec OTOH requires at least syntax documentation for all standard utilities to be present on the system.
