Included mods silently fail when lacking a dependency.

[MerchantPug]

Can be replicated by loading up Farmer's Delight Refabricated 2.2.5 with a version lower than Fabric Loader 0.16.7.
If this is the case, the loader will silently fail to load Porting Lib (a dependency that requires Fabric Loader 0.16.7 or higher).

I know that this can't really be fixed for old loader versions, but it would be nice to have new loader versions actually spit out the error, so that this doesn't happen again.

A temporary fix/fix for devs to make for now is to implement the dependency in their fabric.mod.json. If this won't be changed, this should be the solution and should probably be documented somewhere.
