I'm hoping that T139683: "Impression diet" needs to be turned ON by default will be implemented soon, and as a result, the function of the impression diet counter will become more relevant.

I visit a lot of wikis in the course of a day. For example, during the last few weeks, it was not unusual for me to drop by all 17 of the Wikivoyages in a single hour. And the typical result is that yet another person is running yet another sitebanner, and that banner appears at every single one of the wikis, and has to be dismissed – manually and separately – from every single one of those wikis.

Please make the "impression diet" counter interpret "fourth wiki I visited today" as "I've already seen this banner three times, so you can leave me alone already".
