I guess but it feels like such an anti pattern. I have to tag every thing that uses the template system with ng-cloak and that assumes the angular css loads before the HTML which can still not be guaranteed it's just more likely.

The worst part is many default values could be displayed but now we're hiding sometimes large junks when for the best UX you should show as much of the page as possible.

Ultimately just not a fan of any template engine that relies on being fast enough to hide and replace values in the raw HTML.
