making a debarked log texture with a treated wood look would be really neat, and easier to include in some builds than vanilla logs!

I like to leave these basic material decisions to blusinrize. IE's gonna be there in 1.13 and later, so he may want to add something like this, and a small deco mod should not collide with that.

this isnt basic material, its just for aesthetics, i think hazard has made textures for treated logs but they're unused.

It might become basic material then the 1.13 stripped wood logs can be used. Logs with bark are seldom impregnated/treated. I somehow refrain from adding it, intuitive thing. Sorry ;)
