"Shrimp organics" as in toxins? Not if food quality shrimp is used...better in ways than actual fish food which has preservatives in theory.
I mean, we get a whole bunch of dead stuff on LR -maybe even dead shrimp - but dead sponges, blobs of goo...they are all organics...some of which are in some ways actually are toxic yet totally natural. This is a "ecosystem" we are setting up and you get organic waste in there...and other stuff consumes that organic waste (clean up crews) whether it is a dead animal or animal waste or whatever.
Bacteria colonize the surface of the shrimp and "eat" the proteins...this releases the ammonia...which is the "food" for other types of bacteria as mentioned. Other microbes, protists, various microscopic worms, etc would continue the break down of the shrimp - all a VERY natural, normal process found in the environment (thank goodness or we would be surrounded by eons of accumulations of dead animals and plants). There is nothing wrong with it. Except that once the ammonia spikes most people remove the shrimp before it breaks down into a blob of goo - but more for appearance sake then anything else.
The accumulation of detritus in tanks from decay could become an issue in tanks without enough cleaners, water changes, filtration, over feeding, overstocking etc...and leads to issues, yes. Absolutely agree, from experience

But this is an overall problem not related to using a shrimp...you'll get plenty of organic detritus from LR alone too....and in poorly designed or maintained tanks, it may cause a crash...but not due to cycling with a shrimp. Simply a long term accumulation and failure of the system itself from design faults.
I would agree that die off should be enough to spike the ammonia...but in cases where it doesn't, I am a big fan of pushing it with some sort of ammonia source, most commonly, shrimp.
All the above, JMO

Cycling is always a fun discussion

except, perhaps, for those who would call themselves "normal."
