The PR is likely OK to be merged with just subset of tests for default Python and Database versions without running the full matrix of tests, because it does not modify the core of Airflow. If the committers decide that the full tests matrix is needed, they will add the label 'full tests needed'. Then you should rebase to the latest main or amend the last commit of the PR, and push it with --force-with-lease.

How does [webserver] default_wrap get passed to the frontend after this change? I thought that's what the wrapped meta value is for. Now it does not seem to be used anywhere? See Airflow.code in views.py.

That's a good point, I must have missed that. I've added the isWrapped meta value back - otherwise the default_wrap value won't be used.
