I'm pretty much sure that this won't work. Do you have any docs / source code where angular-addon is specified?

When you use ember cli to create an ember addon it automatically tags it as an ember-addon. This causes the npm package to show up on ember sites that use it to identify ember packages.

I don't know if the angular community is doing something similar.

Allright. Right now angular-cli is based on top of ember-cli. And yes, angular-cli plugins are incorrectly shown on emberaddons.com. The troubles are caused due to this line of code:
https://github.com/ember-cli/ember-cli/blob/ae5e72614e40f5e6dd57463e526c65da899fde07/lib/models/addon-discovery.js#L206

There is more discussion here:
angular/angular-cli#55

As you see, your commit would break the "angular-cli" addon which is unfortionally tagged with "ember-addon".
