Good question. I would say yes to an extent as it’s still in an area where it can get wet.
I imagine if those components could not get wet they would have placed them inside the cabin.
Just my guess.
Washing Engine Bay

I am really surprised with how many are really worried about causing electrical problems. I have washed the engine bay of most of my vehicles over the years (now 65) and only had 1 minor problem, but that was on a used car that was really dirty and I did get pretty aggressive with the power wand at the car wash. I guess if I am going to wash the bay I have to drop at least half of the splash shield on the bottom. Or try and have the car on a slope.

You might be forgetting that cars back then were not computer controlled with all these sensors and sensitive electronics of today...It might not show up after a cleaning, but months later as some moisture might work its way into connectors over time...I think the main purpose of the engine shield is to protect from water splashing up into the engine compartment when driving in the rain and snow, and not just for aerodynamics....Just be cautious....
I would only use distilled water since that is less likely to damage electronics, and only dampen your cleaning tools. Don't soak the engine bay. And of course disconnect the battery and leave it disconnected until it dries. Personally, I would only clean it if the dirt is caked up to the point that it will start insulating heat and if it also gets on moving parts.
