I don't think there is such thing as 100% steady wood since they are porous and made of fibers that can dry or moisten along the year and seasons change. To someone who dig high action and stiffer strings tiny changes wouldn't be felt, but if you use lower action though it's almost mandatory having to adjust the truss rod twice a year at least...
All my basses behave like that since I changed the way I set their strings decades ago and I can't see this as a problem. I try to check up my health regularly and keep my car fine sending it to mechanic just because things get old or slightly change by use and the only way to keep them in good shape is constant care.
The only difference I see on my Rogue is that it always shows any little rattling or execution mistake I made because it is so transparent and enhance anything I do (for good or bad). Some basses can hide minor string noises but Alembic basses can be unforgiving and will show every little nuances. The good side of it is that it pushes me to improve my technique and made me learn how to set truss rods.
I supose you already read Must Reads section, if not, go for it.
To complement, some fellows related that some necks are so stiff that their strings can't bend them enough to truss rod's counter force be usefull. On such cases is recomended to force it to bow for sometime - truss rod fully loose - until it gets used to a new shape. When it assumes this new geometry, it will have sufficient up bow to be compensated by truss rod.
