While it is nice for certain houses to have PvP circles, some people don't want to constantly have to walk around them, and in some houses such as the Battlemage Keep, there is barely any room to move around with the circles there. I believe it would be a nice addition to the game's functions, whether it be in the spellbook, as a housing option or maybe even as Castle Magic to be able to shut off PvP circles so they cannot be used (and preferably if they vanished to allow for furniture to be placed where they were.)
