If your page loads are slower than 200ms, I'd actually suggest having modals. Or at least some way of progressively showing more information (toggles, accordions, etc.) that stay on page.

SPA page loads can get really slow, which can frustrate or disorient users. Having too many page loads to sequentially drill down your info architecture can get really annoying for users. If your pages are 1 or 2 layers deep in your architecture, and the rest is shown in some way within the page (again, modals are one way to do it), as a piece of "fleeting information", your users will appreciate it.
