You can use mithril.js without m.request, but then you have to dispatch redraw events when you finished handling the request[^1]. It also provides a promise API for web requests in old browsers, i.e. without fetch(). If I choose not to use m.request, I would have to find another XMLHttpRequest wrapper and bind it to Mithril.
