When reloading resources/data on a singleplayer world with an intentionally missing loot table, the output log prints the following warning:

Couldn't find resource table my_namespace:items/custom_item

This report is not about getting a warning. I did that on purpose. What this report is about is the fact that the output log uses the terminology resource table instead of the expected loot table.

While I'd like to think this is a hint at things yet-to-come (mob tables, structure tables, etc), it could just be a naming error; hence this report.
