Intune side loading of apps to Android for Work profile for development use
With the device admin deprecation ensuring the adaptation of Android for Work the requirement to test applications within their Android for Work environment will become ever greater. Currently the only way to deploy an app to the AfW profile on Intune is by deploying via the Play Store. When developing an application it is not practical to do this for every time you wish to test your app. For testing and developing apps that make use of conditional access and security related features of Intune's protection it is important to have the ability to side load apps via USB to the AfW profile.
Other MDMs permit the side loading of apps to the AfW profile via a policy setting. This would of course only be required by those who develop apps and it is not suggested that this would be a general requirement for all users.

Intune is even more invasive than you describe. It not only blocks the "WORK" partition, but it also blocks the "PERSONAL" partition from side-loads. There should be an easy way to enable side-loads for specific work scenarios, and for heaven's sake, enable the user to do whatever the **** they want on their own personal phone as long as it is in the personal partition.
