It doesn't mention a date.

It only says 'may'.

It asks for an email "For a Microsoft enabled work or school, personal Microsoft, or GitHub account", which is not particularly clear.

The form and data goes to some 'hubspot.com', rather than to Microsoft. It is default-blocked by ghostery as a tracker.

The feature looks really interesting, the promo site and the experience of using it is, to use the technical term, poopy.
