Comment (by boonebgorges):

 #5394 is a reminder to remove the data at some point in the future.

 I'm leaving this ticket open while I work out some of the details of the
 migration tools, especially in conjunction with #5296.

 As for the other kinds of 'last_activity' metadata used in BuddyPress, I
 think we should refrain from making further changes for now. Blog and
 group last_activity is still stored in the respective meta tables, but
 those tables are much, much smaller, and there are generally far fewer
 groups/blogs than user, so the scaling issues are much less significant.
 Also, a scan through the plugins.svn.wordpress.org directory shows that
 many more plugins make direct reference to *group* last activity than to
 *user* last activity, so a good deal more work would need to be done to
 ensure backward compatibility and to educate developers.

 In the upcoming weeks, I'll write a post for bpdevel about the transition,
 with recommendations for devs.
