Yes, great suggestion. It's currently implemented in the beta Android app, just need to get registered with the Apple Developer Program and get iOS working.
Because Curio saves client-side, it opens the app and renders the page briefly though. Not sure yet if there's a better way to do it.
I loved using Omnivore, and I've found so far in building https://curi.ooo that you can actually do a lot of the legwork in rendering webpages client-side (even on mobile) so that the server-side processing is just used to simplify the HTML. Obviously I'm nowhere near Omnivore's scale but so far costs have been extremely manageable.
That's so unfortunate--I've also used Pocket for a decade+. I had the Omnivore app installed on my phone as a replacement for the other infinite feed scrolling apps.
I'm actually working on an open-source alternative at https://curi.ooo if you're interested in checking it out. It's a work in progress, but I'm building it primarily for my own use because I'm frustrated with all these services shutting down.
The Kobo integration you have is interesting too, wonder how I could support that use case...
