Adjustments from the original mod:
Dragons can be farmed for dragon's breath every 4 days, using a glass bottle
Dragon eggs are found in loot chests now, or in the case of the water dragon egg, an elder guardian drop
Dragons follow players carrying precious gemstones and the like, though they also follow players with fish
Other notes:
To start hatching an egg, right click it with flint and steel
Dragons are tamed with fish
Dragons can be bred with meats
Dragons can be ordered to stay in a spot using a bone
Don't expect a whole lot of support, but feel free to commit PRs if needed.
If anyone asks, this uses a different fork from the other Dragon Mounts mods out there, that in turn was derived from the original repo. As a result, it has kept the same license. So yes, you can port to fabric, provided you use this fork.

Fabric 1.16.* build is being discussed with someone. Though this fork does allow you to make one.
