According to the Wikimedia PageView statistic tool
Did you literally use https://tools.wmflabs.org/pageviews , or have you asked for real requests data? The pageviews API doesn't count requests to the OAI-PMH endpoint at all, because they have "content-type: text/xml" while text/html is required: https://meta.wikimedia.org/wiki/Research:Page_view#Definition
Only people with access to https://wikitech.wikimedia.org/wiki/Analytics/Data/Webrequest#wmf.webrequest can extract data on how much it's used.
