Well, if you have a barred door, unless it is a very flimsy bar, I am not sure how you would expect anyone to "bash" it open anyways. Unless they are a half giant. I get the locks.
Now, if it is barred...how does Nenyuk get in? And if they can get in, what is to keep a thief from replicating that?
This is the idea, it would be next to impossible to get in when barred, short of uninstalling the door or assaulting it with titanic force. A player could log out with some confidence that, whilst their character is at home and in their bed, their bed, dresser, table and three bags of obsidian slag, won't disappear and leave them in a situation where they grasp for how to respond.
You don't burglar a house with people in it unless you're brazen, you wait for them to depart. If they've departed, the door is secured only with it's limited value lock, and thus, open to invasion. Invade to plunder, invade to lie in wait for an ambush, invade to nap on their comfy couch, whatever the case, learning the basic routine of people should play into the role of a rogue, be they thief, murderer, pervert, or all.
For violent home invasions, you would required SIGNIFICANT strength to break a door-bar, and an advanced knowledge of how to throw your weight, as represented by STRENGTH and the BASH skill. It would be loud, potentially with adjacent room echos, especially INTO the WHOLE apartment being assailed, and cause the landlords to alert the authorities, but should still be possible for those brazen enough to risk it.
If the person isn't at home or logged out, the door is only secured by lock and would be easier to bash open, but have no less noise/echos/alerts involved.
When door is simply locked (player active and out of their home), access would be more or less unchanged, except with the advent of violent access (BASH) as an alternative to finesse (lock picking). Kicking open a door held by a bone or chitin latch would not be done casually (BASH skill requirement), but wouldn't necessarily require herculean strength (celf infiltrator using that BASH skill). No damage on fail.
When door is barred from within (player at home or logged out at home), access would be restricted to violent access of a much higher check for success than otherwise. Potentially with a chance to inflict damage on fail, in proportion to applied force, based upon your BASH skill. Higher = better chance of success, and reduced damage on fail.
Nenyuk gets in, in the same way they change locks instantly: Magickal ninja locksmiths. If we can hand wave this, we can hand wave how they unbar apartments for new renters. It's a trivial thing, and not a detail I would sweat over, especially if BASH vs DOOR may become a player option for PvP RP situations, ie hostage situations, etcs, where waiting on staff animations of nenyuk may not be practical to begin with.
Tbh, the code changes required to account for EVERY aspect of doors, locks, and applications of various forces, would be impractical, at least imo. With the skills already in game and, I presume, some additional hooks in their code, barring of doors, bashing of doors, and general improvement in both dynamic gameplay and player satisfaction can be achieved, at a much, much reduced time/work investment.
It is like, I suppose, advanced rock, paper scissors, weighted towards player satisfaction, at the cost of requiring a little more thought and effort from everyone involved.
Edited to reassert that it would, as well, eliminate the constant problems, associated with apartment murders: Door bars could be unlocked or locked from within by anyone, without a key. It not only eliminates apartments being 100% sure murder rooms, but opens significant inroads to betrayal via seduction and other social means.
