This is a Hermitcraft inspired SMP that just started season 3 and it feels really fresh and fun.

The server uses Simple Voice Chat so people can talk in game without having to leave Minecraft. There is Audio Player so you can use custom music discs and goat horns. They also use Carpet to add stuff like renewable deepslate and player bots so you can AFK farms.

There are cool cosmetic things like Tool Trims and custom model support plus a server side skin system so you can change your skin with a command. Image2Map lets players turn pictures into maps which is really good for art and signs.

The server has a bunch of datapacks. There are more mob heads and player head drops. Elytra trims and armor statues let people decorate more. Silence Mobs lets you quiet mobs with a nametag. There are smaller blocks in the stonecutter and wood can be used in the stonecutter too.

Recipe tweaks let you change things like dropper to dispenser universal dyeing sandstone dyeing and downcraftable nether wart and ice. Blaze and Caves advancement pack adds over 1000 new advancements so there is always something to work on.

From what I can see this server is for players who like long term survival and building up a world together with a lot of small quality of life changes instead of crazy mods.
