I'm not sure that's such a huge problem. HTTP routing provides a wonderful architectural seam so that we can use different solutions for different domains like `/profile` and `/document-editor`. We can create rich client-side experiences without creating a monolithic SPA. And as long as we make sure we have those architectural seams we have the flexibility to decide.
Organizing my HTML into pages is the easy part. The hard part is the rich client-side experience: things like building a sortable/filterable table with a rich datetime picker where the data is displayed dynamically in a chart with zoom/pan capabilities. That's why I build SPAs: I've already bit the bullet to get highly dynamic client-side code, it's just as easy to construct my pages client-side as well.
