I have noticed a few fungus gnats that have either drowned in a broms water-filled cup, or perhaps just naturally passed and happened to land there. Now, since they inevitably rot... would the brom absorb the nutrients from the decomposing matter through their leaves?

I'm not absolutely sure whether they can absorb the nutrients this way, but I do believe so. Don't take my word for it though. I used to think it was a bad thing that flies would drown in the brom cups but now I know it's not bad at all. Probably would feed the tads in there too if there are any.

It takes a while for bacteria to break the bugs down into a usable state for the plant. This process would definitely be hurried by tadpoles eating them and deficating in the water. If no tads, I occasionally flush out my broms, as they can get pretty stinky when filled with rotting organic matter.

the "tank" variety bromeliads get most of their nutrients from detritus and dead insects in their cups, so if it is a tank type, just leave them in there.

I have no knowledge of whether non-carnivorous bromeliads can obtain nutrients from dead insects or detritus within their cups.

Here is an interesting article about two genera of carnivorous bromeliads.
