I totally understand that problem. From the GM point of view I don't really get random dungeons. I always want to know the reason WHY such a thing was built, why it's still there, why the traps should still work...

I somehow always feel like dungeons are made by this guy(s) https://www.youtube.com/watch?v=Cwu1rCjb1Fk

So I incorporate them seldom and only when there is plausible reason for why they are here with the very rare exception of some random happenstance every few years.

Interestingly, as a player I don't care about those things at all, I just want to battle some undead or other random monsters :D

But to your map: I don't think that's cheating at all. If there is no special reason why this dungeon should look a certain way, then random generators are a totally reasonable starting point and if they don't generate something really strange, you don't have to change the layout at all!

Sounds about right
