i don't really see them lining bunk up like hay bales.. but i'd be really surprised if many LP's weren't working on extractions already.
1. to get a nice supply ready for when it's allowed
and
2. to give them some experience in doing extractions/having their setup tested and working, before it becomes allowed (so they're not behind the ball like they were with growing
)
law says they can't sell them. doesn't say they can't practice making them
eventually will be legal (and likely more popular) only foolish to not be getting your feet wet.
