Hence why we never bother. We don't bother using buildings in a city because they are often unusable... wouldn't do any good at all... or open to being griefed which honestly isn't worth it... We don't bother asking for anything much anymore as it's 99.9% either denied because they "don't deco" or takes so long that you'd have to have it planned so far in advance that your Governor term would be over before you got it approved.
As I stated in my previous response, if you want deco for the sake of deco, then no, that is not something we are going to put resources behind. If it is in the context of an event that is unrecurring, then you can contact the PEC. They are more than willing to work with you and can request most everything EMs can (sans rewards) for their events. That is why we have the PEC, to take the burden off the EMs to handle player events and the requests associated with them so EMs can continue to focus on shard wide responsibilities. Any event is going to be open to griefing, but there are some safeguards we can put in place to limit it.
