The source of the error while merging is that vertical-collection’s custom treeForAddon emits a CSS file. It shouldn’t.

IMO the entire treeForAddon in vertical-collection is trying too hard to be clever and should be scrapped. Using Rollup here actively subverts our ability to analyze and optimize.

You can workaround by neutering the entire custom treeForAddon hook like this:

const { V1Addon } = require('@embroider/compat');
const Webpack = require('@embroider/webpack').Webpack;
return require('@embroider/compat').compatBuild(app, Webpack, {
  compatAdapters: new Map([[
    "@html-next/vertical-collection",
    class extends V1Addon {
      customizes(...names) {
        // this causes us to never detect a customized treeForAddon and therefore never run it.
        // the treeForAddon in this package does dubious things, and we end up more correct
        // without it.
        return super.customizes(...names.filter(n => n !== 'treeForAddon'));
      }
    }
  ]])
});

The torii issue is unrelated but I made a PR to fix that too.

Yes, those warnings are pointing out real problems where addons are trying to import nonexistent things. They are warnings and not errors because nobody is actually trying to use the nonexistent things.

It would be very helpful if someone wants to make PRs to those projects to clean up the warnings. It looks like the test-helpers one was already done here: https://github.com/emberjs/ember-test-helpers/pull/580
