I really hope this will not be the case.
It's a real shit show for a small business to correctly setup their MDM and account sync. One of the hardest parts is getting those shitty devices into the Apple registry, i.e. connecting the device with a Business (Account).

There's a good issue (#21536) which explores possible ways to implement explicit inlining. Sadly, the proposal got closed without any change.
