A subscription model for a browser seems like a very, very niche market to me - but then that's the vim angle.
For me, hard to justify $15 for a relativity feature-lite browser. You would need a stronger value proposition.
I think most of these features can be reproduced for free on any other browser. Split view is neat but I do that already with chrome and spectacle, both free.
Getting used to the new keyboard shortcuts (you can choose the old Spectacle shortcuts as well) took a few days but had less conflicts and I prefer it now :)
