Rationale
Once a frontend app is converted to frontend-base, it is expected to be loaded as one of many such packages in a proper SPA. In other words, index.html now applies to several apps, not just one. As such, it no longer makes sense to expect each app to modify the header.
Furthermore, each deployment's index.html is now entirely part of site configuration, so there's no need to have code alter it dynamically.
As such, we're deprecating the use of react-helmet and any other methods that modify <head> items directly.
Removal
Any uses of react-helmet or any other methods that modify <head> items directly.
Replacement
The way frontend-base deployments work allow operators to modify index.html directly, and to maintain those modifications under version control. See https://github.com/openedx/frontend-template-site.
