Hi Baloo Uriza,
The destination:street tag value was transferred to the destination tag according to our workflow. At this point in the OSM wiki (https://wiki.openstreetmap.org/wiki/Item:Q1221), there isn’t any definition of when the destination:street tag is used, but our team adhere to the logic according to the proposal from Minh Nguen (https://wiki.openstreetmap.org/wiki/User:Minh_Nguyen/destination:street)
We would appreciate If you could share your insights about this tag. We would really like to learn more about the use of the ‘destination:street’ tag. 
In an effort to gather a wide range of opinions, we have taken the initiative to open a discussion on the forum https://community.openstreetmap.org/t/usage-of-the-destination-and-destination-street-tag-with-the-street-name/101788
Your participation in this discussion would be most welcome!
Best regards!
