It is no longer possible to directly open a contact, e.g. from a list of search results. Instead one must choose "Edit contact" from a menu on a Contact Card. This has a serious negative impact on productivity. The earlier registry settings to "TurnOnLegacyGALDialog" are no longer applicable.
This change in functionality has engendered many complaints online, e.g.

Please provide a simple option (not a registry tweak) to disable Contact Cards and open Contacts directly.
