So, as I suspected, Fast Pair code was deleted from AOSP because it wasn’t being used by anyone.
And because it wasn’t being used, it was just taking up space unnecessarily. Although HalfSheetUX was only a few megabytes in size, Mainline modules are served to many millions of people, a decent portion of whom are on metered connections.
Note: This has no implications for the Fast Pair feature you’re already familiar with. Fast Pair started out as a feature bundled in Play Services and will remain that way for the foreseeable future. This news just means there’s no longer an open source version of Fast Pair.
Removed from system and moved in an automatically downloaded package doesn’t make it smaller nor use less data. The opposite.
