Description
ember-template-imports is an implementation detail of a feature, where those implementation details are being phased out.
For example, ember-template-imports is not used within the v2-addon blueprint (with rollup -- there is a rust plugin that handles the transform, per RFC: emberjs/rfcs#933), and @embroider/vite uses that same plugin in apps, and actually breaks with ember-template-imports present (one too many transforms are happening).
So, I think Glint should also use https://www.npmjs.com/package/content-tag
However, because how Glint handles <template> is an implementation details, there is another approach as well. There is a javascript implementation of content-tag used in this PR:
