Allow layouts to provide dynamic regions

Hi @larowlan, the video you've linked to twice on here isn't viewable. It looks like you have to be part of the Drupal Association Slack? Can you repost the video so we can see how your dynamic tabs works?

Sure

Also, I recommend joining the slack, the community is a huge part of the power of Drupal

Thanks, that's helpful to see how it worked.

I couldn't get signing up for Drupal Slack to work before (though I'm a new Slack user). It required either a Google or Apple account or an @association.drupal.org email. The "Continue with Google" method wouldn't work. But I found the link under "Joining" here → and was able to create an account on there. Thanks.

AFAICT @larowlan showed in the blog post he created 3 years ago at https://www.previousnext.com.au/blog/creating-layout-plugin-dynamic-regions that this is already supported?

@Luke_Nuke: can you confirm that your use case can indeed be achieved without modifying Drupal core?

Can we close this issue? 🤞

That would be great news and +1 for what @WimLeers sad: If the scope of this issue is already covered in core let's move on and close this. Would be great if @Nuke_Luke can confirm this. Apart from that I will go and test now to confirm. Other users who can confirm that is works already would be helpful too. Regarding our policies → I set it to PMNMI for now(?)
