That is actually very uncommon for the typical user.
Outside of photographers, who is going to do this? What percent of the web are photographers (real photographers... not "here's what I ate for dinner" photographers)?
Even if you somehow got 1% of the total web population, wouldn't that still fall into uncommon?
Compound this with the vast majority of web images are not works of art where you have photographers trying to dissect how the image was shot and I would bet uncommon quickly goes to once in a blue moon.
If you run a photography site then obviously the metadata is important to you and they would consciously keep it.
