My criticism is actually about lack of mobile support. I think it's not a good practice to invest years of effort solving a problem in a way that's fundamentally incompatible with mobile. Already nearly most traffic to wikipedia is mobile, and the share is growing.[1]
Browser vendors seem better positioned to solve this problem. Indeed, my reaction to this was I've been doing this with Safari for years already (3 finger tap on macOS, light or long press on iOS). On wikipedia and all over the web. But I can see why Chrome/Firefox users would love this feature, if this is their first encounter with it.
Mobile keeps growing indeed, but around 45% of our pageviews are still on desktop. Here's an overview on how this has changed in the last half decade: https://www.mediawiki.org/wiki/Wikimedia_Audiences#/media/Fi...
(I'm the data analyst who has been working on this software feature, and also keeps track of Wikimedia's reader traffic in general.)
