@marcwrobel Thanks very much for making your first contribution to Spring Boot. I have applied the changes to 2.5.x and merged them forwards through 2.6.x and 2.7.x into main, picking up changes that were specific to those branches along the way. I don't think any of your improvements were lost along the way, but please let me know if I have missed something.
