This step highlights caveats of using VPC-SC with push subscriptions

Beware of limitations when using push subscriptions with VPCSC [1] such as:

You can’t update existing push subscriptions, they continue to function but aren’t protected by VPC Service Controls
Custom domains don’t work, you can only create new push subscriptions for which the push endpoint is set to a Cloud Run service
You can only create new push subscriptions through Eventarc for Eventarc workflows
