Misago is only forum software that doesn't count threads views. I should fix that.
Simplest solution would be to just increase views counter for a thread on every request, but more complex approaches to the problem exist. For example, Discourse only increases views counter when last view was before a specified time. They even do it per IP address for anonymous users.
Ehrm actually flarum doesn't count too. (except with the 3rd extension, which is bad.) 🤓
I don't think the views are necessary. It is not important in either the flarum or the misago system. I don't miss it now.
My benchmarks are Discourse, Invision, XenForo and all of them are counting threads views.
Its also something I would like on my own forums to spot which threads attract the eyeballs.
