## 📚 Context

We initially merged the multipage apps PR with the `ui.hideSidebarNav` config option defaulting to
`True` to use the option as a kind of "feature flag" (we need the option either way in case we ever want
to turn off the nav component and instead build one into Cloud).

Now that we're closer to the release of the multipage apps feature, we can toggle the option to enable
MPAs by default.
