Please create an empty wcpolyfill asset, and remove dependencies from core assets.
There are few:

"dependencies": [ "wcpolyfill" ]

[Fedik]

Better add empty in to /build/media_source/plg_behaviour_compat/removed.asset.json.

Thank you for the work on this, it made in before beta!

@dgrammatiko Can the media/vendor/webcomponentsjs folder be removed on update? Or do we have to keep it? Am asking because working on the deleted files and folders lists in script.php.

[dgrammatiko]

Delete it!

For deleting obsolete files and folders on update see #45928 .
