Can you combine Ionic CDN and @ionic/core


is it ok to include Ionic via CDN and include some features using import of @ionic/core (e.g. alertController)?

I am using a bundler (rollup) to create a js bundle to include in an index.html that uses the CDN.

To me it seems ok, as I only import some features and not the full story.

Does the CDN also include the alertController? It seems not to me, looking at the Javascript reference?
