There was a poll a while back that was confirmed by Kevin that the map brick king was going to be added back but since it needed to be fixed via hammer editor it might have not been on kevins priority list at that very second. That being said I have taken it upon myself to try and help along the process by doing the edits already.
The changes for the map:
*Bosses spawn was moved to the side of the map opposite the reds in the upper area
*Bosses old spawn was removed and sealed shut
*Removed the func_nobuild in the small area to the side of the map
*Added func_nobuild to path jumps in the small area on the side of the map
With these edits, hopefully brick king can be added back sooner
