I think antifingerprinting means that browsers are constantly re-loading and rerendering tons and tons of resources. The web is much much slower than it could be in theory. If you have an siloed app then you don't need to worry about that and can reuse everything. You open a new tab and nearly everything displays instantly (except the different car or whatever you're displaying)
This would also decrease your network bandwidth load. So a win for you and your customers
