No Excerpt with Layout Editor

Hi, I already learned that the excerpt has to be set manually if the layout editor is in use in a blog post.
Here: https://kriesi.at/support/topic/blog-excerpt-not-displayed/
To be honest, I think this is not a very smart solution and there should be a way to have an automated excerpt.
The current mode causes a plus on work and the risk that changes, made to the text, are not displayed because the excerpt is not updated.

I really would appreciate if the TEAM offers a smarter solution to this issue.
