Wikidata edits are measured real time and hidden in the number of edits are the number of qualifiers added.
As there is a new set of statistics in town, their numbers are measured as well. Currently there are 23.176 qualifiers on statements. As you can see in the graphic, they are growing fast. So far there are no bots who add qualifiers.
When the bots know how to set qualifiers, it will make the available information more understandable and relevant to humans.
