Volume going down automatically

IOS upgrade seems to have added feature which is lowering volume (to MUTE almost) when attention is not on phone (Settings -> Accessibility -> Face ID and Attention -> Attention Aware Features).

When ON, it's lowering even the ALARM volume miserably low. Why would Apple do that? Alarm is supposed to wake you. Secondly, if you leave your phone to the table for few minutes, the phone call ringer volume is going down to almost silent. Why would I want that feature?? If I want silence, I would silent my phone by pushing button. But even when I push silent button, I would want Alarm ringer to be in max volume. This is ridiculous.
