Air compressor fittings

I'm getting ready to paint the bottom of my car and I didn't buy a fitting for my gun, so I was looking at what I had to make sure everything fit together. Right now I have a 3/8 hose but I noticed all the quick connect fittings go to 1/4.

This compressor was gifted to me so I asked my dad why he did that and his response was "thats pretty standard"

But is it though? That seems kind of odd you're purposely go to a smaller fitting reducing flow even though you already have the large hose.

Right now I'm thinking about replacing all the fittings to be at least 3/8"
