+My current thinking is that when a repository does not have a preferred
+content expression, a content sync could avoid adding content to it.
+
+This would avoid surprising behavior after the transition, except for
+repositories that did at some time have a preferred content expression set,
+but one that no longer reflects the use of the repository.
+
+However, current users of `sync --content` (or of annex.synccontent) do
+expect it to fill their repositories that don't have preferred content
+configured. So would a sync that defaults to content syncing then need to
+behave differently than an explicit `sync --content`? Or should changing
+behavior in that case also be part of the transition?
