Yes, I created Mithril. I also co-authored Fusion.js[1], which - in contrast - is about as "big boy" as a framework gets (and mostly works w/ the React ecosystem, if you're curious). We use the latter at over 100 projects at Uber. Mithril fits in a similar camp as Svelte, and it does offer APIs for HTTP requests and routing out of the box. I've worked on projects before where I literally only had Mithril as a sole dependency (and this was with supporting IE10). Fusion.js solves a lot of complexity-at-scale problems but it does so at a trade-off of not being nearly as geared towards standards tracking as systems like Svelte and Mithril.
