Vanilla swallows item asset errors in loading, NeoForge re-add?

[Tslat]

With the new setup in 1.21.4, Vanilla is now silently swallowing errors for some things related to loading in item assets.

For example, if you don't have an assets/<modid>/items/<item_id>.json file at all (which is required for all items), the game will silently load in the missing texture/model, but won't print anything to log.
I believe it's also swallowing some others, such as if the target model the items asset designates doesn't exist (although it does print errors if the target model is invalid json

Any chance NeoForge could add these for usability? Especially given this is an entirely new asset location and system, users are going to be incredibly confused.

The most likely reason why vanilla doesn't log anything anymore is that there is no way to know all missing models during reload anymore and while there is currently still a way to check at least the default model for all items during resource reload (which is what my PR adds), the intention once items are data-driven seems to be to not require doing a resource reload when connecting to a server with custom items, at which point it is impossible to check pre-emptively check for missing models.

Right but even when the item tries to use the asset, it'll fail out with an error model and not tell you why

It's not even just for presumptive assets
