Signs- pretty sure they already are? I always start with wooden signs BP. And there are a few cosmetic sign BPs that are DLC/you can buy. I actually appreciate greatly this form of microtransaction and would request more of them. Truly non-mechanically advantageous microtransaction BPs are fun. Unique little furniture things, and such. But I digress-
I disagree with this mainly because its not really necessary. 1 hour of barrels and you’ll have every one of those BPs, anyway. Comfort items and planters absolutely give gameplay advantages and I don’t see why the current system needs changing.
I guess its a minor enough thing to not matter terribly.
