SVG feels like a very underexplored and underused territory. You can do so many things with it. It really depends on your imagination. But you’ll possibly need to “hardcore” a lot of stuff, so yeah, depends on the use case as well.
One thing i'd like to see is an entire site built with SVG and JS without any HTML at all. It's possible but i haven't seen anyone do it yet.
so how can you know it's actually possible?
Browsers will render SVG files. SVG files can link to other SVG files. Just need to configure the server to serve SVG by default — most servers don't but it's an easy config change.
