Absolutely. Wet, heavy, sticky snow. If ever any type of snow would adhere to the airframe it's wet stuff right around the freezing point.

Not to mention, where did the plane come from? Was it just brought in from a six hour transcon that has cold soaked every square inch of it? Is this an early morning departure where the sun has just come up raising the temp quickly after sitting overnight with cold fuel in it? So many variables, there is a reason why ANY frozen precip, or any precip with temps below freezing, and your company wants you to get sprayed, and so does the FAA. Why overthink this?

My company makes such a big deal about this that if the FAA is calling snow on the field but it's no longer snowing the company gives you two options, either ask for and receive a special observation or call DX and mark it on record over a recorded line that there is no snow on the field. It's a huge deal.

In your example, do I think it's a safety issue? No not really. The airplane will be fine most likely. We tend to way overdo it now in regards to de/anti icing, I agree.
