Yep, good explanation; but to add to this…

The important factor here as far as what an individual uses is the tracked metrics. When a browser looks at a website, it identifies itself and its engine. Therefore actually using an engine other than Chromium is important because it goes into use stats across all websites the individual visits.

And like with all collective endeavors, while an individual contribution is insignificant, the whole is made up of those individual contributions. It also only takes a few percentage points of users for a business to in theory want to avoid excluding those users and thus keep them developing for multiple browsers.
