Most of the ember issues that we have had are not with log roll out. They have been random pops and bursts that shoot a hot ember out the stove door. Some types of wood do this fairly regularly. Advocating a violation of the manual and code is not a solution. Several options have been given that are simple and will not affect traffic patterns.Personally i wouldnt worry about it. If you load north/south you shouldnt have any logs roll out and the door should only be open when you're tending the fire so any embers that happen to get spit out you can take care of right away. Unless you have kids or something you're worried about leaving the door open id just leave it.
