Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
Yes, your observation is correct.
This is mentioned in the retirement announcement you shared as well.
Your existing VMs that use default outbound access will continue to work after this retirement, however, we strongly recommend transitioning to an explicit outbound method
Kindly let us know if this helps or you need further assistance on this issue.
Thanks,
