Nah, there's a Crypt:$ map with a building hidden behind trees, though I seem to remember you saying you didn't ever go in Crypt. Not to mention the dozens of vaults with things hidden behind walls. Not that I'm disagreeing with your main point -- Crawl isn't Metroid -- but it's not entirely uncommon, though most of the "secret" stuff is in extended (see: Pan Lord vaults, Tar endings, etc.).
That said, the elephant Lair ending really does feel especially cheesy; I'd almost like it better if it was more like the iron golem Dis map, where you entered a large space with several statues and they all awoke as soon as you opened the door. There's just too much going on in that vault, between the doors and the anaconda and the forest loot. I like it, it has good flavour and I've enjoyed playing through it, but I can see where it'd be criticized.
