The Blame mod is no longer maintained as its main purpose was the dynamic registry parsing stuff. Since so much changed in 1.18, the Cyanide mod took over and does a much better job with worldgen issues, esp. JSON, datapack, and codec issues. However, there are a few things which blame did which Cyanide did not and Not Enough Crashes seems like the appropriate place for these:

• Command stacktrace printing
• Feature, structure, processor crash reporting
• Missing loot table
• Missing structure NBT files
• Entities added to biomes with their weight or min/max spawn groups at invalid values

Seems reasonable

If anyone would like to contribute to NEC this is a good place to start
