Hi! This is a conclusion I came to after trying to figure out why Autumnity wasn't getting variant chests and ladders in my modpack. I read on another issue that these variants were specifically implemented as Woodworks compat. I think it'd be great if they could also function as compat with Quark (chest and ladder) and Building But Better (ladder only).
Here's a comparison with BWG's Maple wood in JEI:

(I'm using a mod called Every Compat to automatically generate variants for other modded blocks, if you're curious about all the other maple furniture.)
If you don't want to worry about syncing the items with Quark's config, then I think a config option to force load the maple chest and ladder would at least be nice to have. I know that I could probably just disable Quark's variant chests and ladders and add Woodworks to the pack, but I just think this little extra bit of compat would be a nice way to avoid that hassle.
Edit: While this issue is about Autumnity specifically, it might be worth doing the same thing for Atmospheric, Environmental, etc. since they presumably handle their Woodworks compat in the same way.
