Because you have the same version for multiple Minecraft versions, you cannot tell which exact version someone has by looking at the mod list in a log.

You could append the Minecraft version to the version field in the fabric.mod.json. Sodium, for example, does 0.6.0+mc1.21.1. Similarly Fabric API does 0.109.0+1.21.3.

A tighter Minecraft dependency may prevent users from running the wrong version.

You should also add source code and issues links to Modrinth page.

And switch to the fabric-api mod ID for clarity.

Made this issue because I saw someone use the 1.21 version on 1.20.1 which crashed.
