I saw that warning when I started to set up my phone and I immediately stopped. If anyone needs to contact me about something urgent they can do it using the work approved IM client that doesn’t require a profile to be installed.

If it does get to the point where I need to have access to my company email, I will have a separate device.

That being said, if my phone was erased, it would only be a slight inconvenience, I can restore from backup.
