Hello! Unfortunately, I can't say that HardcoreSK is fully supported.
I myself really love HSK and only play with it, but my computer is old and testing on it is just awful. Here are a few problems that I know: PVP definitely does not work (due to the expansion of the combat system), pawns are not transferred normally (they appear as hostile). The rest is just very little tested, maybe the rest works.

If I understand you correctly, then I can create my own server.
What if only players with the same HSK build of the same version play on my server? Problem with PvP actuall? Or problems only if players with HSK playing vs players without it?

Maybe commynity HSK will help u with testing? :) They are friendly sometimes :D
