In previous versions Spark was adding its version to the resource string when user was first time launching Spark and new profile was created. But this string hasn't been updated dynamically based on version changes, so this feature was removed in 2.7.1 to not confuse users. It can be added as a separate option (same as "use hostname as a resource"). But it should always update itself based on the current version in use. Preferably including build version also (x.x.x.xxx).
