nobody stops you of "deicing" your wings from "dandelion" type of DRY snow.... but you may run afterwords in different problems, like freezing of areas that were not frozen before.
Said "different problems" are specifically addressed by the LOUT table: Lowest Operational Use Temperature, below which the fluid does not meet viscosity requirements. The LOUT table is included in the same publication as the HOT table.
It is clear-cut and in writing. There is no guesswork here and no supposition. There is no "but what if?" Either "you do" or "you don't" get sprayed. If there is contamination on the critical surfaces, they need to be de-iced. If the temperature is below LOUT for the fluid used and there is contamination on the critical surfaces you don't fly.
