Comment (by jorbin):

 I think there is a step that needs to take place first and that is for 4.3
 and earlier to no longer be receiving security updates unless this can be
 done in a way that allows for the term splitting to be completed before
 the DB change. This will be a rare (first that I can think of off the top
 of my head) instance where a site will not be able to "just upgrade" from
 any version to the latest version and if we are going to do that, we
 should do all we can to ensure as few sites as possible are running these
 severely out of date versions.

 Additionally, for the breaking change to go in I think we will need to
 make sure that the updates API never offers whatever version this is in to
 sites below 4.3.

 Finally, for folks looking for more on the history of shared terms, this
 speech from @boonebgorges covers the history very well:
