Taglighting
by TeamVoided
Taglighting moves block behaviour into data tags, so server owners can change what certain vanilla blocks allow without editing code.
What it does
Taglighting replaces a set of hardcoded rules in vanilla Minecraft with game-based tags. Sugarcane hydration, the blocks that can be placed by endermen, the blocks that can build a nether portal frame, and the blocks that make snow and iron golem bases are all read from tags instead of fixed lists. Behaviour that used to be fixed in code, such as nether sprouts only being placeable on a short list of nether blocks, can be adjusted the same way.
The mod also changes how pistons and sticky blocks work. Some blocks can be made immovable by pistons, and others can behave like slime or honey blocks, carrying mobs along when they are pushed. Because these rules are tags, datapacks can edit them without a separate mod. Taglighting runs on the server alone, and the MIT License covers the source code, which is open source.
Taglighting needs Fabric API and Fabric Language Kotlin. The mod is published for Fabric only, across the game versions 1.21 – 1.21.10, and the latest file is 1.1.0+1.21.10 for 1.21.10.
Key features
Tag-driven sugarcane
Sugarcane hydration rules are read from a tag, so the blocks that count as water sources can be changed.
Tag-driven placement rules
Endermen, nether portal frames and the golem bases use tags, replacing lists that were fixed in the game code.
Immovable and sticky blocks
Some blocks can be set so pistons cannot move them, and others can move mobs along with them like honey blocks.
Datapack editing
Server owners can edit the tags through datapacks, adjusting vanilla block behaviour without writing code.

How it compares
Old Piston Sound Engine is client-side only, open source under the CC0 1.0 Universal license and published for 1.21 – 1.21.5, so it changes sounds rather than block rules. Snow Golems In Hot Biomes is server-side only and under the MIT License, with files for 1.21 alone, and is not open source. More Snow runs on client and server under the CC0 1.0 Universal license, with files for 1.21.1 only.

What the author says
--- Finally feature X is now a tag instead of being a random hardcoded thing. Yipeee! The mod changes a lot of hard coded behaviours in the game to be based of tags instead. For example, Nether sprouts can only be placed on a hard coded list of nether blocks. So if you wanted to plan them on soul sand you would have…
