Traps on the other side of the door

As I was browsing through the various quest books, I noticed how especially the Elf Pack seemed to feature traps directly behind doors - including Falling Block Traps, sometimes even at a door to a room that has no other exits.
According to the official rules, you can only search for traps in the same room or hallway as the character doing the search. I've searched the forums, but couldn't find much about this specific topic. As it is, with the official rules, traps behind doors are pretty much sure-fire traps. The Falling Block Traps are especially deadly in this respect, if there is no other exit and the Hero decides to jump sideways instead of backwards through the door he came into the room (a backwards move which by the EU rules is actually forbidden). In my opinion, this seems to make those traps more dangerous than elsewhere on the board.
Also, it seems a bit ... weird that a Hero wouldn't be able to search a tile directly on the other side of the threshold, while at the same time if a Hero stands on one corner of the long hallway at the outer edge of the board and there's a trap all the way in the other far corner, that the Hero would be able to detect it by searching just fine.
Thoughts? Or if I am late to that party, where has this particular issue been discussed before?
I'm considering a house rule during play to allow Heroes to check tiles directly behind a door - but that doesn't remedy the situation if there are monsters on the other side, as that prevents searches of any kind.
