Apple introduced new beta distribution channel in recent iOS beta. Now beta could be installed on devices with developer Apple ID.

At the same time Apple is deprecating beta device profiles, which means that developers will have slightly less options to install OS beta.

There are couple of situations which developers could be in.

Using same Apple ID for personal and development purposes

In this case, installing beta might affect iCloud data associated with account. That might include photos, text, HomeKit and other Apple services.

This might result in data being inaccessible from previous OS releases or even destroyed, especially when installing early beta releases.

If using beta versions is needed, developers might need to have separate Apple IDs for their personal and development devices.

Using different Apple IDs

While this is recommended setup, it would still affect development pipelines, if developer decides to install later betas on personal devices.

Current workaround would be to use public beta releases which are currently available for non-developers.
