Hello @Roel-t thank you for this PR, just a heads-up: it might take a little while for the core team to look at this, because the current focus is getting 7.0 shipped. We won't merge features at this time.

[Roel-t]

@yannbf Thank you!! So how do I go on merging the PR? I see danger JS is failing and giving npm notice created a lockfile as package-lock.json. You should commit this file. though I don't see changes to the package-lock.json file. Any idea?

[ndelangen]

@Roel-t I merged in next, let's see if CI approves now.
