Anyone trynig to fine-tune material settings? Noone?
Regardless, here are the mappings for 1.17.1:
mappings_extract.txt
Just open it with your favourite text editor/browser and use "find" function to look up the translation; the english one mainly matches names_of_blocks.
Taken from Yarn mappings (c).

P.S. ".default" gets applied to everything without a category, i.e. some modded blocks, barrier block, etc. And, the nice settings like "SNOW", obviously, don't work.

Here are the translations for them:

field_11547	WOOD
field_11531	ANVIL
field_11535	GRASS
field_11543	WOOL
field_11548	SNOW
field_11533	METAL
field_11532	LADDER
field_11529	GRAVEL
field_11537	GLASS
field_11544	STONE

whatever
