I was reading about the changes in v5.0, and scared mons with no valid squares to move to will now attack. So digging out a 3x3 closet, standing in the middle, dropping a ?oSM, and sending in some dragons no longer seems safe. There are 8 squares for the dragons, 6 can be sent in, meaning that some of the dragons won't be able to move and will therefore attack, right?
but I think you can be a bit safer if you dig some extra squares out. You can dig

and be relatively safe from the dragons, right? I mean there's still a chance that 4 dragons will surround one dragon, but this is relatively unlikely, and will hopefully not persist for many turns. It will take a little longer to kill the dragons as they can now spend time on squares where you can't reach, but they'll eventually wander next to you, right?
Is anyone doing this? Reverse gencoding dragons was a common way for me to get DSM. in 3.x.x
I also sometimes use the soko ?oSM if I'm immune to the breath weapon. This seems decidedly unsafe now, right? I guess it's very unsafe if the door to the scroll is intact, and marginally unsafe if you break the door down?
